Unity of the Faith
of the Church Throughout the
Whole World
By Saint Irenaeus (c. 202)
The Church, though dispersed throughout the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: She believes in one God the Father Almighty, maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaims through the prophets the dispensations of God, and the advents, and the birth from the virgin, and the passion, and the resurrection from the dead, and the ascension into heaven in the flesh of the beloved Christ Jesus our Lord, and His future manifestation from heaven in the glory of the Father “to gather all things in one”…
The Church, having received this teaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves
it. She also believes these points of doctrine just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth. For, although the languages of the world are dissimilar, yet the import of the tradition is the same. For the Churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Lybia, nor those which have been established in the central regions of the world. But as the sun, that creature of God, is one and the same throughout the whole world, so also the preaching of the truth shines everywhere, and enlightens all men that are willing to come to a knowledge of the truth. Nor will any one of the rulers in the Churches, however highly gifted he may be in point of eloquence, teach doctrines different from these (for no one is greater than the Master); nor, on the other hand, will he who is deficient in power of expression inflict injury on the tradition. For the faith being ever one and the same, neither does one who is able at great length to discourse regarding it, make any addition to it, nor does one, who can say but little, diminish it.
