I asked this question on an SSPX Discord server and there was a mod who responded that it was completely okay to join the military, that the Catholic Church has never called any war unjust, and that you can serve in those wars. He didn't say this outright, however. For example, he really nitpicked the fact that I started my question with "can" rather than "is it morally permissible to". All Catholics have free will, and so we CAN join the military. He used a strict interpretation of what I said (because I wasn't particularly precise) in order to refute my argument and open the doors very wide to involvement in war and military. He also never mentioned the fact that you will be surrounded by people who swear and make dirty jokes. I could sense that he was using sophistry to trap us in our words without anyone noticing, because he always liked to use charitable language and say the word "kindly" and "please" a lot. I believe he also defended the Vatican declaration criticizing the use of "co-Redemptrix" by specifying that they weren't literally against it, all the while being subtle and charitable.
I asked a question recently about whether it's true that you can get a dispensation for marrying your uncle or aunt according to the catechism "My Catholic Faith", and the answer so far has been yes, but we'll see to that later. Another man says their great great grandparents got a dispensation from Rome to marry their first cousin.
Although involvement in the military is not always a hard "no", it's obvious that in general it does not seem moral to willfully put yourself into an American foreign war or to go into the US Army.
Well, this is the SSPX Discord server for you. But I will admit that I should've been more precise with my words. I'm really only on this server nowadays to test and see what they actually think about all these weird things.
Previously, I went on a side tangent because I remembered how they treated me and the injustice angered me.
There are several reasons it could be a good idea for you to join the army, it's 1)
Making connections. 2)Learning how to fight, so that you can defend your family and yourself. 3)Get a job, if really you cannot find another occupation.
In those troubled times, being from the military could save you and your family's life, especially if there is a cινιℓ ωαr. If a cινιℓ ωαr happens, people who cannot fight will have a really hard time.
Amassing
actual power to change the world. The reason christian traditionalists lose all the time and Satan wins is because too many Catholics are far too scrupulous. There are 1 million abortions every single year in the USA. In the world, there are more than 77 million abortions every single year.
In the last 20 years, that means 1.5 billion children were murdered.
1 billion children got murdered, meanwhile Catholics are worried about swearing in the army? Don't you think this is completely ridiculous ?
You should be concerned about becoming as powerful as you can be as a man , so that in the future you can protect your family from the countless disgusting creeps that plague this world, and maybe save actual people.
You need to think carefully about whether joining the army is the best way you can serve God and do good in the world.
