Ecumenism is a movement that wants everyone who believes in God to all get together no matter what their doctrinal beliefs are.

Yep, the whole concept is if you believe in God, you're one of them.. The Devil believes in God. Satanists believe in God. They must be welcome in the movement to win the cities for god. Or to put it in Catholic terms: Satanists have objective truth - in that they believe in God.

Here's a little treat for the Once saved always saved crowd to chew on: John 3:36:

o pisteuwn eiV ton uion ecei zwhn aiwnion;
The [one] believing in the Son has life eternal;

o de apeiqwn tw uiw ouk oyetai zwhn,
but the [one] disobeying the Son will not see life,

all h orgh tou qeou menei ep auton
but the wrath - of God remains on him.

Again, Obedience is everything.
