I disagree, no where did Jesus or the Apostles describe a distinct hierarchy. What he did describe were people with gifts from the Holy Spirit that were affirmed by the congregation for leadership.. and that leadership could be taken away by the congregation. Even when Paul appointed Elders and sent them to a particular church, but he sent along a letter with them asking the church to examine the new elders for fitness prior to following them.
The early church had a Presbyterian form of government, where a church is run by elders with different gifts (no priests or pastors).. it was up to them and the congregation to affirm those gifts and follow their lead.
As far as Peter, he was the first to confess that Jesus was the Christ and that confession is what the ekklesia is built on. One cannot be a christian without that confession...
Anyhow, Romes hierarchy is very similar to the hierarchy of Mithraism... its customs like sacraments, priests, etc.. are all identical also, with only the names being changed.
So basically, you are a follower of rebranded Mithraism... that is all.
I see your theology is based on throw a lot of things at the wall with the hopes that something will stick.
