One Holy Catholic and Apostolic Church

For other uses, see Christianity, Christian denominations, or Church (disambiguation). The Christian Church is the universal institution embodying the Christian faith, the religion based on the worship of Jesus of Nazareth as the son of God. The concept as it was known beginning in 30-33 A.D.,expresses the idea that the followers of the religion can all be seen as part of one single group. Although today there is no single political entity recognized by the secular world as the unique Christian Church,; each of the Orthodox and Roman Catholic churches claims to be the unique church established by Jesus the Messiah. Protestants would hold that the concept is justified by the notion that the Church is ultimately headed by Jesus Christ who acts as the unifying figure for all who claim to follow Him. The phrase "The Church" in its widest sense (as "the Body of Christ") has a similar breadth.

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.
