The Church is everywhere represented as one. It is one body, one family, one fold, one kingdom. It is one because pervaded by one Spirit. We are all baptized into one Spirit so as to become, says the apostle, on body.

The orthodox believers in God are divided into two camps, one of which maintains that the existence of God is as demonstrable as any mathematical proposition, while the other asserts that his existence is not demonstrable to the intellect.
