What is the only thing required for salvation?
One can only become a Christian Apostate if they was first a Christian to begin with.
The argument that they never was a Christian to begin with doesn't work because they can't be called an Apostate in the first place unless they was a Christian to begin with!!
I also know that there are people who play Church and might even believe that they are a Christian.
Before any of these questions matter in the OSAS subjects and the other touchy subjects in Hebrews etc, we need to define the original question!
