Unfortunately the "Reformed Theology" 4 & 5 point Calvinist preachers teach that God Himself is the Author of sin by His decree in action not permission which makes Him the one sinning and yet we're still responsible for it. They also teach evanescent grace which is a ghoulish idea written in Calvin's writings, that I don't think Calvin himself taught but that his successor changed after his death. Evanescent grace suggests that those who go apostate had only gotten a short term grace that looks to all as if they were born again that God shows Himself to them like His true children but then He basically sends them the delusion Himself so they perish. They deny free will so God would then lie to people and let them think they're His and then send them a delusion so they perish so you really can't know for sure you're elect at all and you'll find out after you die. It's one of the most ghoulish blasphemous things I've heard and I've dealt with leaders in universalist/emergent church/WOKE/liberal theology churches, name-it claim-it/prosperity gospel types, Catholic/Orthodox and works only 5 point Arminians and have heard, seen, read and had face to face confrontations with some nasty heresies out there but such an idea is even nastier & highly respected "reformed theology" preachers like John Piper who is a 5 point Calvinist & teaches "Christian Hedonism,", R.C. Sproul, 5 point Calvinist who died in 2017 but his teaching live on and his son R.C. Sproul Jr teaches it too along with the head covering legalism, James White is a 5 point Calvinist hotheaded teacher who has a podcast, Voddie Baucham, a 5 point ghoul who calls babies "vipers in diapers," John MacArthur is a 5 pointed full blown psychopath & he's called "The Pope of Protestantism."
