Did you get to the part where St. Paul says:
8 But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. 9 As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed. — Galatians 1:8-9
Seems to me that a better response would have been to let him be accursed, rather than accursing yourself.
Hmmmm that I’ll need to think on, though I’m missing how I’m accursed because a group of friends talk about our faith and help each other with questions. Thanks for that (sincerely, not sarcastically).
