Yes, even today all 'born again, new creations in Yeshua' - Titus 3:5, put the
emphsis on Galatians 5:5-6 If a MC godly man has never been circumcised should he now be circumcised in order to satisfy requirements of a Messianic Judaism congregation in order to be accepted as one of them? More than a few MJs would say he is not godly until he is circumcised. And so we find religion exists within MJ as well as MC.
A Messanic Christian (pro-Paul) that joins a MJ congregation is generally expected to follow certain Jewish requirements ... like not eating bacon (pork) and other laws of Judaism. Some Believers believe they will become more righteous as a MC/MJ than as a member of a mainline Christian church. Paul goes on to further emphasize (verses 5-6) the importnce of becoming a "faithful new creation in Christ" more so than whether a follower of Yeshua/Jesus is MJ or MC ...
Galatians 5:5-6 (CJB)
5 For it is by the power of the Spirit, who works in us because we trust and are faithful, that we confidently expect our hope of attaining righteousness to be fulfilled.
6 When we are united with the Messiah Yeshua, neither being circumcised nor being uncircumcised matters; what matters is trusting faithfulness expressing itself through love.
Galatians 5:5-6 (NLT)
5 But we who live by the Spirit eagerly wait to receive by faith the righteousness God has promised to us.
6 For when we place our faith in Christ Jesus, there is no benefit in being circumcised or being uncircumcised. What is important is faith expressing itself in love.
Christianity is not so much a religion as it is an intimate faithful relationship with the Lord
