“Not considering scripture inspired at this point it’s based on the historical record of their content.”

"And how do you know the historical record is an accurate and authoritative basis for the Church’s claim?"

It's a matter of pure reliable history:

Testimony of the Evangelists - by Simon Greenleaf (1783-1853)

Are the Gospels Myth?

“It’s a matter of pure reliable history:”

I am not asking when or if the Catholic Church was founded, I am asking what the Catholic Church basis it’s claim to spiritual authority on.

The Catholic Church claims a significant amount of spiritual authority... that they are God’s sole representatives on the earth and hold the keys to mankind’s eternal destiny, & etc. These are no small claims.

By what authority to they make these claims?

What do they base their claims upon?
