Origen — as excerpted in the Catena Aurea on John 13:12-20

“(t. xxxii. 10.) For he that receiveth him whom Jesus sends, receiveth Jesus who is represented by him; and he that receiveth Jesus, receiveth the Father. Therefore he that receiveth whom Jesus sends, receiveth the Father that sent. The words may have this meaning too: He that receiveth whom I send, had attained unto receiving Me: he who receiveth Me not by means of any Apostle, but by My own entrance into his soul, receiveth the Father; so that not only I abide in him, but the Father also.”
