There can be but one Divinely instituted Church in the world.
That Christ established a Church to teach, govern spiritually, sanctify and lead men to salvation.
That the Church of Christ is a spiritual organism rather than a mere organization.
That its organic character is derived from the life principle of its Founder, Jesus Christ, who gave it life and is its life. In this sense, the Church is Christ and Christ is the Church.
That the Church is a living body, instituted by Christ, the Holy Spirit indwelling; a visible society of believers, partaking of the same sacraments, governed by lawful pastors under one visible head, Peter and his successors.
That four marks distinguish Christ's kingdom of heaven on earth. They are made known in the Creed?"I believe in the One, Holy, Catholic, and Apostolic Church."

Peoples of all nationalities obedient to one universal authority in faith and morals.

"The enemies of the Church themselves die and disappear, but the Church itself lives on, and preaches the power of God to ever succeeding generations" (St. Augustine).
