IMO, like other Pelagians, their "god" is not God, but Satan.

God Is.

He is Sovereign in all things including salvation.

He is Holy.

He expects His people to sit under sound teaching and to reject heresy and heretics.

He saves by Grace Alone, through Faith Alone, in Christ Alone, according to Scripture Alone and for His Glory alone.

We are Totally Depraved. His Grace is Unconditional and Irresistable. His Atonement was Limited, not in its power, but in its scope, having been intended only for the elect. And the Saints will Persevere.

This is not some reformed, partisan rant; it is the CLEAR teaching of Scripture.

By teaching salvation by works (notably baptism) they put themselves outside of the boundaries of historical, biblical Christianity, arguably more so than even Rome.

By denying all the historical creeds, they acknowledge they do not believe what, almost by definition, all or nearly all Christians have historically believed.

By claiming that all those outside their sect are still in their sins, they both blaspheme the God who saved every person who was ever saved, and also faithfully perform the work of Satan, by falsely accusing the Saints.

They also sow doubt and fear among new and/or poorly taught Christians (which, to be clear, is most of them.)

Have no fellowship with the unfruitful works of darkness. But obviously do pray for them, be open to sharing Scripture with them, and know that while they are almost certainly still in their sins, that doesn't mean God can't or won't save them in the future.
