Nicene and Post-Nicene Fathers, Vol. IV:
Writings in Connection with the Donatist Controversy.: Chapter 6

p. 439

Chapter 6.—9.  Libosus also of Vaga says:  "The Lord says in the gospel, ‘I am the Truth.’ 1273   He does not say, ‘I am custom.’  Therefore, when the truth is made manifest, custom must give way to truth." 1274   Clearly, no one could doubt that custom must give way to truth where it is made manifest.  But we shall see presently about the manifestation of the truth.  Meanwhile he also makes it clear that custom was on the other side.
