1 Corinthians 11:19
Douay-Rheims
For there must be also heresies: that they also, who are approved, may be made manifest among you.
Tertullian
Now if there are no heresies at all but what those who refute them are supposed to have fabricated, then the apostle who predicted them must have been guilty of falsehood.
