quote-I agree we should get the day of Passover correct if we are going to celebrate the resurrection (though Christmass is basically out for me), but if the specific day was so important that those who get the day wrong are believing a false gospel then that is akin to elitist Catholicism and cults. That itself is deception.
When Rome has teachers that teach Mary has come down here and given us Promises, we can test those against Scripture and see whether they are true or not.
They can be shown to be false-lies. So, I would have no problem calling that mary a false prophetess. A fake.
Problem is that mary points to Jesus. Scripture says no lie is of the truth.
So if Rome’s mary can be shown to be a fake, what Jesus is she pointing to? A fake Jesus?
Is there any scriptural warnings about false christs, false prophets, another Jesus or another gospel?
Let me ask it this way-
Is it possible Rome has a false Mary and false Jesus
or
do they just worship Jesus falsely?
Both can be the case but that is not and has not been the issue, but that of applying 2 Cor 11:3 (different spirit Jesus, Spirit, gospel) to those who simply hold to Good Friday Holy Saturday and Easter Sunday as Rome does. However, this practice itself does not mean they are preaching a false gospel. Despite your additions to what Paul preached, he did not mention the specific days that Christ died on, and making belief in these necessary for salvation, as you inferred, is a false gospel.
