>> You’ve just denied that Christ was sinless.<<
No, I didn’t say that. I said “He carried our sin” by being born of Mary. Yet He remained sinless.
1 Peter 2:24 and He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed.
No, how can he be sinless if he’s tainted with original sin.
Original sin, means that he has sin in him, and that’s wrong.
Christ was sinless and free of original sin. This is basic Christology. Really basic stuff.
