Evidence of his influence is still seen.
Of course his influence is still seen today - in the same way the opposite influence of
the Ebonites and others is still present when they went in the opposite direction. Both groups within the Church had to be addressed...
Thankfully, theology itself in the Early Church doesn't lend itself to the idea to assume that
anything pertaining to the OT was automatically within the negative and only that within the NT was good. For the heresy of
Marcionism tried to divorce the God of the OT from the God of the NT in a false scenario ...but the Early Church valued OT practice (more shared
here,
here,
here) and thankfully combated him...
Technically, as it concerns the OP, Marcionism would tend to show up (if equating it with the spirit of lawlessness) whenever there are aspects of making it out as if the God of the OT is not the same as the God of the NT. In example, if God commanded Capital Punishment in the O.T. (which we all acknowledge), and if that makes the god of the O.T. a "vengeful" God (as opposed to the God of the N.T.), one would just of adopted Marcionism in the area of capital punishment: the gnostic "dualism" approach of the testaments where the god of the O.T. is the god of evil matter, and the God of the N.T. is the "loving", "merciful" God.
And even outside of Marcionism, there were others promoting the spirit of lawlessness whenever they would try to add on to what God commanded of believers in the New Covenant and say that it was a matter of keeping the Law - for in doing so, that'd be a matter of sin. This is what the Ebionites (certain camps of them, specifically) were guilty of opposite of Marcion when they advocated the keeping of all aspects of the OT in order to avoid being lawless as they saw it....for going past what Yeshua noted and what God promoted is what lawlessness is about.....and lawlessness was never about not following all things solely in Mosaic code. When God gave different laws to different groups, that was the Law they were to be for - and to go back to a previous system of law was disobedience in itself - as well as promoting the wrong law.
1 John 3:4
[ Sin and the Child of God ] Whoever commits sin also commits lawlessness, and sin is lawlessness.5 And you know that He was manifested to take away our sins, and in Him there is no sin.
Sin is what lawlessness is defined by - not systems of law given at one time or another. To those under the Law of Moses, to go past that was SIN - and at the same time, there were others not bound by the Mosaic Law (like Jethro of Midian and others like Noah ) who were given differing requirements/laws (as the Gentiles were outside of Israel ) and to not be faithful to that was SIN - for them. And likewise, in Matthew 7, many quote that saying "That's the way Yeshua will speak to the Gentiles since they were lawless (i.e. not under Mosaic Code!!!") yet the context is one where he was speaking primarily to a Jewish audience - warning them of false prophets who were doing many things that were approved of/asked by the Lord...but it wasn't His HEART nor was it His Will for them.
There's an excellent paper on the issue elsewhere if interested - as it address the Anti-Semitism present in Marcionism and other systems that developed to combat it and yet went in other directions. ..for
the paper explores Ebionism and Marcionism, two early church heresies which depict the two most antithetical forms of the Judaism-OT and Christianity-NT breach in early Christianity. It addresses Ebionism's philo-Semitlism and Marcionism’s chagrin for the Jewish roots of Christianity - both shown to be antecedents to certain contemporary heretical conceptions ...and both having a corrective found in Paul's metaphor of God’s revelatiory-redemptive olive tree (Romans 1/:/7-24) which aptly describes the dual necessity of the root and the branches, that is the Old and New Testaments.
