"Sigh... so much for finding a place to belong. I've always felt out of place and have yet to find my niche." Extroversion - introverts feel most comfortable with themselves, which as isolated entities have no need for a "niche"
"I enjoy going to church and small family parties" - comfort with communal belonging and closeness to family (introverted sensing, possible extroversion)
"Why?" - lack of ideation/looking for factual statements (S)
"Our life experiences make us who we are. Only our Father knows what’s truly in our hearts. God is the only one who knows the path that will bring us peace, if that is in fact His will. Heaven is our only promised peace.
I now understand why it is so difficult for all of us to come together on philosophies. Why people are divided in our world, our country, our communities and even our faiths.
However, I am now more at peace knowing God is in control of my life.
I’ve learned to continue seeking advice and comfort when I feel lost. I now stop and review what I know in my heart to be true. I use external advice and comfort only if it aligns to the teachings of the Bible" (screams Si)
"My Enneagram is 2w1" - could apply to ESFJ/ISFJ just as easily as ENFJ/INFJ
"Wow, you guys are mean! So much for being nice to the newbie

" - Sensitive to criticism and expresses disagreement immediately without seeking further detail (F, possibly E, not P)
Firm, declarative statements (J)
"Now the only question I've asked here is F or I !!!!" - desire to control the flow of conversation (Je [EJ], extroversion)
"I have never been close to an INTP, but if this is how blunt and rude they are.. I don't see how an INFJ would fall for one" - lack of knowledge on Typology, going off of visible facts (S), lack of ideational insight (no N).
Just my opinions. Reading My True Type by A.J. Drenth may help you understand the system a bit better, since you obviously want to understand yourself better through its lens. I agree with the others that I don't see a lot of abstract verbiage, as Absurdity noted.
Could there be something here about the son who acts like an ENTJ? Aversion to strong Te is signs of Ti, which again any EFJ has. I think what we're really tackling here is the N/S dichotomy. You're obviously EFJ.
