That is a very ungodly vanity. You would be better serving God to care more about whose side you were on than on whose side God is on.
Logic and human reason are poor substitutes for the Holy Spirit and faith when it comes to choosing an authority. As dangerous as you claim it is for Catholics to accept the pronouncements of a Pope as infallible and the basis for a Catholic doctrine or dogma, it is significantly more dangerous when you choose yourself as that authority because it is in the pursuit of self that sin and error are born. Buddhists look inward to find God, Christians look to Christ.
Peace be with you.
The Holy Spirit renews a man’s mind to know the things of God and to lead him in all righteousness.
Pray for the Holy Spirit’s guidance.
“Vanity?”. Lol. God’s truth has been called far worse. Read your Bible.
