Paul often faced challenges in applying his theology. In Colossians 2:18, he says: "Let no one disqualify you, insisting on asceticism and worship of angels, going on in detail about visions, puffed up without reason by his sensuous mind." In Romans 12:1-2, he writes: "Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. Do not conform to the pattern of this world, but be transformed by the renewing of your mind." Additionally, in his final letters, he writes in 1 Timothy 6:20-21: "O Timothy, guard the deposit entrusted to you. Avoid the irreverent babble and contradictions of what is falsely called 'knowledge,' for by professing it, some have swerved from the faith. Grace be with you."
1) So, he is trying to correct several problems that occurred in the application of his Theology.
2) Older Christian denominations, with their resilience, have managed to address these issues, at least in part. Many of the newer ones, though not all and without generalizing, tend to embody the "being" of Jesus in an emotional and passionate way. Yet, the highest form of Christian theology teaches that we are to be in Christ just as He is in the Father. Jesus, after all, set an example for the lost sheep of Israel—those who did not know the law—showing them how to truly worship the Father.
