Christ himself is the way, and therefore he says: I am the way. This certainly is eminently right for through him we have access to the Father. Since this way is not separate from its end, but joined to it, he adds the truth and the life; thus he is himself at once both the way and the goal. In his human nature he is the way, and in his divine nature he is the goal. Therefore, speaking as man he says: I am the way; and speaking as God he adds: the truth and the life. These two words are an apt description of this goal. For this goal is the object of human desire, and a man desires two things above all. In the first place he wants to know the truth, which is peculiar to him; and secondly he wants to continue to exist, which is common to all things. Christ is the way by which we come to know truth, though he is also that truth: Lead me, O Lord, in truth, and I shall enter into your way. Christ is also the way to come to life, though he is also that life: You have made known the ways of life. Therefore, he designated the end of this way by truth and life, about which we have spoken above with reference to Christ. First, he himself is life, for life was in him; then, he is truth, because he was the light of men, and light is truth.
