“Jesus' teaching on the separation of the sheep from the goats is based on the works that were done during their lives, not just on their acceptance of Christ as Savior. In fact, this teaching even demonstrates that those who are ultimately saved do not necessarily have to know Christ.” [http://www.scripturecatholic.com/salvation.html#salvation-I]
If you’re just good enough but don’t know Christ you can still be saved because Christ did after all “open that door”.
I call that blasphemy and anyone who subscribes to that a heretic.
Catholic teaching, you’re doing it wrong.
It’s your church of you, you can declare whatever you wish to be heresy. This of course applies to everyone in your church of you.
I don’t think too many will worry about this.
