22. Anyone who knows what it is about the Lord that “the Son of God” means and what it is about him that “the Son of Humanity” means can see many hidden wonders in the Word, since the Lord calls himself sometimes the Son, sometimes the Son of God, and sometimes the Son of Humanity, in each case depending on the subject of the discourse.
When the subject is his divinity, or his being one with the Father, or his divine power, or faith in him, or life from him, then he calls himself “the Son” and “the Son of God, ” as in John 5:16-26 and elsewhere. When the subject is his suffering, though, or his judging, or his Coming, or more generally his redeeming, saving, reforming, or regenerating us, then he calls himself the Son of Humanity. This is because it then means himself as the Word.
The Lord is identified by various names in the Word of the Old Testament. There he is called Jehovah, Jah, the Lord, God, the Lord Jehovih, Jehovah Sabaoth, the God of Israel, the Holy One of Israel, the Mighty One of Jacob, Shaddai, the Rock, as well as Creator, Maker, Savior, Redeemer-always depending on the subject of the discourse. This is the case in the Word of the New Testament, too, where he is called Jesus, the Christ, the Lord, God, the Son of God, the Son of Humanity, the Prophet, and the Lamb, among other names, again always depending on the subject of the discourse.
