Nicene and Post-Nicene Fathers, Vol. III:
Doctrinal Treatises of St. Augustin: Section 14

14. It follows after commendation of the Trinity, “The Holy Church.” God is pointed out, and His temple. “For the temple of God is holy,” says the Apostle, “which (temple) are ye.” 1801 This same is the holy Church, the one Church, the true Church, the catholic Church, fighting against all heresies: fight, it can: be fought down, it cannot. As for heresies, they went all out of it, like as unprofitable branches pruned from the vine: but itself abideth in its root, in its Vine, in its charity. “The gates of hell shall not prevail against it.” 1802
