“And I believe one holy Catholic and Apostolic Church;”
Isn’t this part of the Creed?
The Four Marks of the Church, sometimes referred to as the Marks of the Church or the Marks of the True Church, are a group of four adjectives describing the true Church as established by Jesus Christ. They are commonly acknowledged by most Christian denominations, as they are included in many of their creeds. The marks are often listed as follows: one, holy, catholic, and apostolic. They refer to four aspects that are intrinsic to the true Church: unity, sanctity, catholicism (or universality), and apostolicity.
