Satan was the first "disgruntled" employee. Martin Luther the second. Peter is the rock upon which Christ built His church. Not Henry, Martin or Calvin. Anything else is hollow.
The Apostle Paul once wrote:
"There are contentions among you. I mean, each one of you says, 'I follow Paul,' 'I follow Apollos,' 'I follow Peter,' and, 'I follow Christ.' Is Christ divided? Was I crucified for you; were you baptized into my name? (...) Who then is Apollos, and who am I, but servants through whom you believed; and each as the Lord gave to him? I planted. Apollos watered. But God gave the increase. So then neither he who plants is anything, nor he who waters, but God who gives the increase. Now
he who plants and he who waters are the same, but each will receive his own reward according to his own labor. For we are God's fellow workers. You are God's farming, God's building." (1 Corinthians 1:12-13, 3:5-8)
Peter is long dead. Many have built their ministry on Peter's foundation, and just because they may not have stayed within the same organization as the Roman Catholic Church does not make it any less rooted in the good news of Christ. In fact, it can be argued that the church in Rome has often wrapped itself up in procedure and ritual-- in many ways much like the old ways of Temple Judaism that Jesus so heavily rebuked in his time-- and lost sight of what was important. That can happen whether it is the church in Rome or elsewhere.
It is no matter if the foundation is sturdy, a poorly built house will still collapse upon itself.
