2 Timothy 4:2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.Excellent. In that spirit, I suggest you check this out:
The Complete Ante-Nicene & Nicene and Post-Nicene Church Fathers Collection: 3 Series, 37 Volumes, 65 Authors, 1,000 Books, 18,000 Chapters, 16 Million Words
Now why would I be interested in what anyone later than the apostles said? Paul said anyone who taught something that they didn't teach was to be considered accursed.
