So Christianity became at once a catholic religion, consisting in the diffusion of great truths and a divine life.

It overflowed the nationalities of Greece and Rome, of North Africa, of Persia and Western Asia, at the very beginning.

It conquered the Gothic and German conquerors of the Roman Empire.

Under Arian missionaries, it converted Goths, Vandals, Lombards.

Under Nestorian missionaries, it penetrated as far east as China, and made converts there.
In like manner the Gospel spread over the whole of North Africa, whence it was afterwards expelled by the power of Islam.
