St. Anselm, Archbishop of Canterbury, gave an explanation for how the contemplation of God leads one to know He exists.
Just as a civil kingdom is a perfect society, so is the kingdom of God: the Catholic Church.

Defenders of papal supremacy and the Solus Petrus hermeneutic often point to Jesus giving Peter the keys. However, the text of Scripture shows that Peter isn't given the keys separately from the other apostles.
