Didymus the Blind
Catena Aurea · Johannesevangelium 16
I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself: but whatsoever he shall hear, that shall he speak; and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you. All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
(Didym. de Sp. Sanct. ii. ult med. inter opera Hieron.) Or He means that His hearers had not yet attained to all those things which for His name’s sake they were able to bear: so revealing lesser things, He puts off the greater for a future time, such things as they could not understand till the Cross itself of their crucified Head had been their instruction. As yet they were slaves to the types, and shadows, and images of the Law, and could not bear the truth of which the Law was the shadow. But when the Holy Ghost came, He would lead them by His teaching and discipline into all truth, transferring them from the dead letter to the quickening Spirit, in Whom alone all Scripture truth resides.
