Its interesting to find how often that the people least interested in hearing preachers are the very ones who most like to preach. More precisely, many of the people least interested in Christian morality are the ones most interested in spreading their own morality, a Christless morality. Christless moralists were essentially what the Scribes & Pharisees, Sadducees & Herodians turned out to be. And, no matter what the religious façade they might masquerade with, to be Christless is to be Godless.
1 John 2:23
Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
He who hates Me hates My Father also.
The broader context of this first verse shows us how these Christless moralists are actually lying antichrists, (just like the Scribes & Pharisees, Sadducees & Herodians, et al who opposed Jesus Christ):
1 John 2:22-23
Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. 23 Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
When they teach different than what Jesus taught, they teach a different gospel.
When they hold up a different leader than Jesus, they teach a different Jesus, a different anointed one, a different Christ.
They have made themselves enemies of the Gospel of Christ.
Every Christ-less moral movement is just another incarnation of the Chief Priests & Saducess, Herodians, Scribes & Pharisees & Judaizers, et al, those well-heeled, well-regarded, white-washed, civic, cultural & intellectual leaders who proved themselves in actuality to be the enemies of Christ and God, wolves-in-sheeps-clothing all. The Word of God records the antics of the Scribes & Pharisees and various other enemies of the Gospel so that we would recognize them in their many forms. Modern Pharisees take the form of "pious and superior" leaders & followers of various Christ-less religions, Christ-less ideologies, Christ-less movements, etc. These are the Christ-ignoring moralists, Godless philosophers, atheists, secular humanists, environmentalists, racists, statists, Christ-less college professors, and "experts" of every stripe who imagine themselves better guides to good than Christ Jesus & His Apostles. They will each end up helplessly in the ditch as all blind leaders of the blind can't help themselves but fall. Just leave them as Jesus said, and they will bring their own punishment upon themselves while Christ & His followers walk on.
