Thanks for the statements and comments.
I guess if we can toss out the issue of the popes being evil for a second.
I think the main question I have is what does Christ mean when he says “I will build my church and the gates of hell shall not prevail against it” (Matthew 18). Is this referring to the infallibility of the papal teaching office ex cathedra? Or is this referring to the body of Christ consisting of human beings?
This quote (from Mt 16 not 18) refers to the ekklesia as a whole - The assembly, the community. So in this sense parts of the assembly or community might fall away (not be saved) but the community as a whole survive.
But a community does not simply consist of a random collection of persons. They are brought together by some commonality. In this case it is Christ who draws them together and charges them to maintain community with each other. He taught them and gave commandments to Love one another.
Jesus also prayed that we be one - as He and the Father are one:
John 17:20-21
20 "I do not pray for these only, but also for those who believe in me through their word, 21 that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us, so that the world may believe that thou hast sent me
How much more united can we hope for than this…The Epistles continue this call to unity with repeated exhortations.
Rom 15:5-6
5 May the God of endurance and encouragement grant you to live in such harmony with one another, in accord with Christ Jesus, 6 that together you may with one voice glorify the God and Father of our Lord Jesus Christ.
1 Cor 1:10
I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment.
2 Cor 13:11
Finally, brothers, rejoice. Aim for restoration, comfort one another, agree with one another, live in peace; and the God of love and peace will be with you.
Php 1:27
Only let your manner of life be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of you that you are standing firm in one spirit, with one mind striving side by side for the faith of the gospel,
1 Pet 3:8
Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind.
Can we lay claim to this biblical kind of unity when different groups teach conflicting doctrines?
Can the Holy Spirit teach that the Lord’s supper is both the real presence AND only symbolic?
Christ’s community needs a way to resolve these matters of conflict. Christ provided for this. The Holy Scriptures not only give us instruction but a demonstration of it in action.
The Papal office is but one part of this apparatus that has developed from simple beginnings.
The RC and the EO have used these methods of governance and council to good effect ( the great Schism being the notable failure). Great pressure has been brought at times to change - to go against ancient truths - to “get with the times” - but the Church has resisted and clung to the Gospel.
Can’t tell if I’ve answered your question or gotten off topic…Sorry…Hope some of this might help.
Peace
