First, it's not necessarily directed at just you though the Pelagian theology you use comes accross to me and (I guess) to cofty that way
Pelagiius beleived that a Christian should be og high morals and uncompromising , even to the death and Augustine disagreed.
I agree with AUgustine that the CHurch is a hospital for sinners and not a museum of saints.
That said, that a Christian shoul try to be better than He was in behaviour and in thought is, to me, clear in the teachings of Christ and the apostles.
Sure we fail and we have to accept that in ourselves and each other, but we should still strive to do better, not because if any moral law or any love, but because of God's love for us through Christ.
