Though the Son was incorporeal, He formed for Himself a body after our fashion. He appeared as one of the sheep; yet, He still remained the Shepherd. he was esteemed a servant; yet, He did not renounce the Sonship. he was carried in the womb of Mary, yet arrayed in the nature of His Father. He walked upon the earth, yet He filled heaven. he appeared as an infant, yet He did not discard the eternity of His nature. He was invested with a body, but it did not circumscribe the unmixed simplicity of His Divinity. . . . He needed sustenance inasmuch as He was man; yet, He did not cease to feed the entire world inasmuch as He is God. He put on the likeness of a servant, while not impairing the likeness of His Father.
