Christ founded his Church on the apostles, the first Bishops. Why is that so hard to believe?
The church is founded on Christ, the Rock.
Peter, the guy you claim as first pope, even says so in his letter.
1 Peter 2:4-8 As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 5 you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. 6 For it stands in Scripture:
Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.
7 So the honor is for you who believe, but for those who do not believe, The stone that the builders rejected has become the cornerstone,
8 and A stone of stumbling, and a rock of offense. They stumble because they disobey the word, as they were destined to do.
