“I don’t know why any non-catholic Christian who does not recognize the papal office to be so concerned about what this pope says.”
As a Christian, I do not see myself as being bound by the authority of the Pope because I do not think he meets the Biblical criteria for apostleship. However, I recognize that millions of observant Catholics do recognize his authority.
Even though I am unpersuaded by the argument of apostolic succession or that there is an absolute continuity of doctrine in the Catholic Church, I do understand that this is a major argument that Catholics have for their commitment to their Church.
And Protestants and Catholics on this forum generally agree on abortion, homosexuality, and the death penalty.
If we could get Catholics and Protestants to ALL agree and refuse to support any politicians who hold other views, we could cooperatively right a lot of the wrongs in this nation, I believe.
It is alarming to me that the world’s largest Christian denomination is drifting away from social conservatism. And I did not think it was possible for official Catholic doctrines to be changed. But that appears to be the case.
That's my point, it seems you don't consider Catholics to be Christians.
And many Catholics are anti-Unam Sanctum; too.
