“St. Justin Martyr emphasized that the Son had no need to be baptized—just as he had no need to be born, to suffer, or die—but did so in order to reveal himself to mankind....”
Or to put it in modern parlance: He was baptized by his cousin because it was his coming out party. And early version of a debutante ball in society circles.

THANK YOU so much for explaining this: "to reveal Himself to mankind." Of course.
Nice to have someone on board who knows these things.
