(a) “Is what we state in the Creed our belief about God, or is it Jesus' belief about God?”

Perhaps Jesus was deluded, we are deluded, or both.

(b) “Is the Book of Revelation ALL that we can possibly know about God and the end times?”

The revelation that ended with the death of the last Apostle didn’t end; special people are in direct contact with the Holy Spirit.

(c) “Is John the Apostle the composer of the Book of Revelation or is it John of Patmos, who is another person?”

The incorporation of a text into the Church’s teaching and Scripture is void if “scholars” question the attribution.

We seem to be discussing post-Christianity.
