That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we saw, and our hands touched, concerning the Word of life
Which we have heard, which we have seen. It was not the hearing of a report, to which little credit is usually given, but John means, that he had faithfully learnt from his Master those things which he taught, so that he alleged nothing thoughtlessly and rashly. And, doubtless, no one is a fit teacher in the Church, who has not been the disciple of the Son of God, and rightly instructed in his school, since his authority alone ought to prevail.
