Neither be you called masters: for one is your Teacher, even Christ.
Read Chapter 23
John Chrysostom
AD 407
Previously when he had asked, “What do you think of the Christ?” it is worth noting that he did not say, “What do you think of me?” So it is here that he says you have one master, and he does not make this subjective by saying “me” but “the Christ.” Yet note that this passage repeatedly speaks of the one master, the one teacher, repeatedly applying the term one. Does this term apply to the Father alone so as to reject the only begotten Son? Is the Father guide? All would agree, and none would challenge it. And yet “one,” he says, “is your guide, even Christ.” For just as Christ, being called the one guide, does not cast out the Father from being guide, even so the Father, being called Master, does not cast out the Son from being Master. For the expression one is spoken in contradistinction to the human way of speaking and within the rest of the creation. The Gospel of Matthew, Homily
And again He adds, Neither be ye called guides, for one is your guide, even Christ; and He said not, I. For like as above He said, What think ye of Christ? and He said not, of me, so here too.
But I should be glad to ask here, what they would say, who are repeatedly applying the term one, one, to the Father alone, to the rejection of the Only-begotten. Is the Father guide? All would declare it, and none would gainsay it. And yet one, He says, is your guide, even Christ. For like as Christ, being called the one guide, casts not out the Father from being guide; even so the Father, being called Master, does not cast out the Son from being Master. For the expression, one, one, is spoken in contradistinction to men, and the rest of the creation.
