A Prodigal child?
Well, welcome him back and throw the child a feast. That's what Jesus' Prodigal father did in the parable. It was Jesus himself relaying that parable, yes?
Oh wait, I see, be like the angry older brother???
Lol, those scriptures have nothing to with the comments being made or how to help someone whose faith is 'weak'.
Corinthians is talking about how all are part of Christ's body but have different purposes. Galatians is talking about circumcision being unecessary for Gentiles and followers of Christ in general. Jude has nothing to do with the article at all.
All out of context and discombobulated as usual.
In reality, Biblically speaking, the Prodigal's Son had nothing to do with weak faith .... Guy just went off to spend his inheritance on drink and prostitutes.
