If Mercury is conjunct, square, opposite, sextile, or trine Jupiter in your birth chart, you’re the preacher. This is a combination that can make you either an inspiring or an overwhelming person to mentally engage with. Mercury rules how we communicate with other people, while Jupiter is about the beliefs and the particular faith that we have in life. So, it makes sense that a Mercury-Jupiter aspect in one’s natal chart gives them a yearning to communicate (Mercury) their faith (Jupiter). But, just how are you doing that? Because, as beneficial as Jupiter can be, it’s not all good, like some may think (just as a feared planet like Saturn has plenty of positives). The downside of Jupiter is over-doing it. With Mercury in aspect to Jupiter, you can very easily get a person who over-does it when it comes to speaking their faith, not knowing when to stop preaching to others.
So, the downside of these aspects is an obnoxious self-righteousness. It tends to be more evident in those with the harsher aspects, like the square and the opposition. The conjunction can go either way, as it’s such a seamless expression of the aspect’s energy that it can either be very positive or rather challenging, often switching between the two. Those with the sextile or the trine seem to understand how to communicate their beliefs without shoving them down people’s throats. But, even they have their moments. Essentially, this all comes from the fact that you have a tough time separating opinions from facts. Mercury is an objective, logical, factual planet. Meanwhile, Jupiter is all about what you believe, which is highly subjective. When you merge the two, you get someone who feels as if what they believe is a fact and that, of course, is not always the case.
This is an attitude that goes all the way back to your grade school years. I think that Mercury represents how we dealt with school, from elementary to high school. And for those with a Mercury-Jupiter aspect, school was not so much a time of learning but of discovering. People regularly associate Jupiter with teaching. But, recently, I’ve come to realize that Mercury is actually the teacher, as it deals with the facts. Jupiter is the guide, showing you the way toward discoveries that are greater than facts. For this reason, Mercury-Jupiter people usually do much better in college (unless they have the square or the opposition) than they did in grade school. In college, you’re encouraged to give your opinions a lot more. With this placement, this is right up your alley. You didn’t want to just spit out the facts in school. You wanted to give your perspective.
As a result, you might have excelled in any sort of subject that required you to think in bigger, broader terms. In high school, the Advanced Placement classes typically require this of their students, preparing you for college, in this sense. You could’ve taken to those classes easily and readily. In fact, you really wanted to as whatever Jupiter touches, there is a yearning to “go big” in that area. So, when it came to school, you did really strive to be one of the smartest kids in your class. Even if you didn’t work hard toward this and other things got in the way, like peer pressures or self-doubt or whatever else, you still had a very idealistic vision of yourself being an amazing student. But, an overly casual attitude might have been the problem. Unless you have a Mercury-Saturn aspect, or Mercury in Virgo or Capricorn, you didn’t really want to work to get to the top of the class. You just thought it would be really awesome to be there.
So, often times, you see the Mercury-Jupiter teenagers who take all the shortcuts to academic glory. You might not have cheated, per se, unless your Mercury is in Scorpio or Pisces, because the “honor code” may have been too important to you. But, instead, you were probably that student who didn’t study or do their paper until the night before or who was very lax about attending class or paying attention while in class. Yet, Jupiter is where we get lucky. So, lucky you: you still had a way of usually passing your classes even with minimal effort. But, this set you up for a learning pattern that showed that you didn’t have to apply too much effort to know something. You just believed you already knew it. It’s actually an amazing mental trick that follows you throughout life: if you approach information with that “I got it” attitude, you are usually able to get an A on the test, so to speak. But, of course, this can only take you so far.
Your academic sloppiness might have frustrated your teachers, at times, especially when you challenged their own grip on the facts. This can turn into downright hubris for some Mercury-Jupiter kids and adolescents. You didn’t have to show your work on that math test, you thought. You got the right answer. The facts behind it didn’t matter all that much to you. It’s also why, when you questioned what the teacher was telling you, you probably didn’t hesitate to speak out against him or her and, likely, in front of the whole class. Having a big mouth is a symptom of the Mercury-Jupiter aspect and this developed early. It’s the kind of thing that could’ve made the teacher feel like you were trying to take over the class. You not only communicated like a know-it-all but like a class-clown, as well, which made it even worse. When you look back and remember that boy or girl in the 9th grade who could never be quiet, stop making jokes, or otherwise go ignored in class, they definitely could’ve have Mercury in aspect to Jupiter in their chart.
All this means that the process of learning, for you, is hard to get through without mouthing off. Mercury-Jupiter people are usually big-time interrupters, as they have so much on their mind that they want to say and are so enthusiastic about saying it. With the harsher aspects, this can get seriously annoying to the other person who is just trying to get their point across. But, the problem is that you’re pretty presumptuous about what they’re going to say. Those with this placement take in just about anything with that “I already know that” attitude. So, even when you’re talking to them, they regularly assume that they already know what you’re going to tell them. What does this result in, though? The inevitable outcome of them getting it totally wrong, either putting their foot in their mouth or making a foolish choice off of what they assumed to be right.
After all, Jupiter doesn’t unconditionally bring us good fortune. Just like they were regular occasions where you failed that test you hardly studied for (even though you hate to look back at your academic record as being anything but positive), there are the recurring moments now, in adulthood, where you “fail” in conversation with others because your mouth and/or brain made you too casual or too careless. Yes, there is a certain bluntness that can also come with these aspects. Again, you see your beliefs as facts. So, you can communicate your honest opinion in such a matter-of-fact way that you don’t stop to realize the damage that it might do. You believing that your friend’s hair looks terrible today or that your boss is a moron or that you’re in the right in your argument with your partner is not the same as saying two plus two equals four. Accepting that you’re not always right is a huge thing for Mercury-Jupiter individuals. If you can’t, then it can establish a barrier in your communication with others that’s hard to cross.
But, this is why I call you the preacher. Whatever your belief is, you stick to it. To a certain degree, all of our beliefs start to feel like facts. Yet, a lot of us can step back and realize that we’re mostly just being subjective. With the Mercury-Jupiter influence, that’s much harder for you. You’re like the person who believes God exists so absolutely that it becomes a die-hard fact. Your particular “religion” or “God” in life (which is what Jupiter stands for) is communicated in this way. That’s why there’s so much conviction behind whatever it is that you say. It’s also why you might end up being a bit too much in conversation, sometimes. People aren’t always in the mood for that fire and brimstone. If you have Mercury and/or Jupiter in a Fire sign, then this can definitely be a problem for you. You get so caught up in your convictions but, again, this is the way you comprehend things. It’s clear that the Mercury-Jupiter aspect is quite a contradiction and it requires a balance between your logical side and the side of you that is pure belief and faith.
Yet, this faith is the good thing about you. We all need faith in life! It helps us get through life, even when all the facts show us that things might not be so great. Since you have Mercury touching your Jupiter, you possess the ability to do this, overlooking the cut-and-dry facts in order to adopt a more inspired, positive mentality, which ends up making wonderful things happen. So, your belief that everything will work out to your benefit (Jupiter) becomes a form of logic (Mercury) and this is truly a good thing. This is another reason why you are the preacher. It’s because you are capable of thinking and speaking in a manner that will inspire others. After all, whether you agree with the preacher’s message or not, he or she just wants to uplift other people. Essentially, this is the way you are, as well. You might stand up on a soapbox a bit too often and you may have an exaggerated sense of right and wrong. But, in the end, when someone else is feeling down, the faith and the inspiration you think and speak with can really brighten up their day.
You make for an exciting conversationalist because of this. Jupiter is about adventure and with Jupiter in aspect to Mercury in your chart, every conversation has the potential to be an adventure. Those with the square or the opposition just often need to work through a pattern of either holding back their intellectual enthusiasm, which will bore and deplete them, or totally indulging in it, which will make them over-the-top in their communication. A more moderate approach can be developed, where you embark on these journeys of the mind without going overboard. With this placement, you love the feeling of never knowing where the conversation will go next. As a result, you are a much more spontaneous speaker, at your best, who loves the freedom of just saying whatever comes to mind, instead of operating on a limiting script. While Mercury-Uranus people speak in a more off-the-wall, weird, unpredictable fashion, Mercury-Jupiter people communicate best when they can be fully unleashed and uninhibited, which does often mean not having much of a filter.
At the same time, this is also what gives you the ability to talk so much. You can think a lot, too, sometimes more than necessary. Since Jupiter is about excess, the Mercury-Jupiter aspect means that you have an enormous amount of mental, intellectual energy. You would probably benefit from doing a lot of reading and/or writing, in order to get all of that out. You are chock-full of ideas, in more than one sense. You’re so full of ideas that it can be hard to figure out which ones to act on first. With Mercury representing our sense of humor, you are also full of ideas when it comes to jokes and making people laugh. For you, humor is freeing and enlightening. Your sense of humor is larger-than-life; not particularly restrained or understated. Even if there are other Mercury aspects in your chart that symbolize a dry or sophisticated wit, there is still a major part of you that just likes it really big, broad, and silly; the more “stupid” kind of comedy. You can be a total goofball, with a big laugh that’s hard to contain and an ability to bring just as much laughter out of others. In fact, others see you as so hilarious that you can even get a laugh when you’re not trying to be funny.
Mercury conjunct Jupiter: You have the potential to be the biggest know-it-all, with the conjunction, as you have the strongest belief, out of the other aspects, in whatever you say and think. It’s important for you to slow down and admit to the facts, sometimes. Yet, your amazing amount of mental faith is why you have such a resilient attitude and can be a total inspirational speaker.
Mercury square or opposite Jupiter: Thanks to having the square or the opposition, it’s hard for you to know, in your dialogue with others, when to reel it in. You might be insufferably opinionated, trying to hold your beliefs back but failing. Understanding when to communicate these beliefs is an important balance, which will allow you to use your words to genuinely uplift other people.
Mercury sextile or trine Jupiter: The sextile or the trine makes you the preacher with the message that’s gentler or easier to swallow. You simply have an enthusiastic, free, buoyant way of communicating with others. Although you usually stand your ground reasonably, you, too, can sometimes get swept up in your beliefs. So, remember the difference between opinion and fact.
