Update on this:
My friend offered me to go to mass with him today. I decided to go (as kind of a courtesy), and we got food at a place close by aftefwards.
I told him during our meal that I was agnostic. He wasn't aware of that before, but wasn't super surprised(he knew I hadn't gone to church much in the past 4 years). I told him I wanted to be transparent and he appreciated that. I also told him I hadn't closed the door on Christianity/Catholicism, and I appreciated him reaching out.
I also referenced a number of things that were discuss in the priest's homily at the mass today(not relevant, but priest was clearly African, and I guessed he was Nigerian, and I was right lol. I feel like a good majority of African priests are Nigerian.). He was discussing evangelizatiion(gospel reading was the "fishers of men" excerpt).
The priest noted that:
-In the end, what an individual can do in terms of evangelization is limited. Conversion ultimately comes down to the relationship between the person and God/The Holy Spirit.
-It is important for a person to listen more than speak
-Disagreement should not disturb your faith, but rather solidify it and help identify it
Overall, he took it pretty well. We talked for a good 2 hours about a number of topics associated with religion(the historicity of Jesus, how Christianity spread, the afterlife, humanism and the value of human life,etc.). Definitely learned a thing or two(he knows his stuff regarding the Catholic stuff, as he should if he wants to be a priest), and definitely want to dive more into a number of topics associated with religion.
He also said he wouldn't mind if i still come to church with him at some points, just for company. He said he was never trying to force the issue when asking about going to church, just wanted to reach about because he cared.
I think I had excessive pre emptive fear of his reaction, looking back at it. Like I said, he was pretty aware that I hadn't been to church much, and my parents don't go much at all either. IDK why I thought he would possibly react negatively.
