God the Father has given His Spirit to Christ, His beloved Son, according to the received humanity. (Because of this He is called also Messiah; i.e., the Anointed.) He has not received His gifts with limits as other saints. For on Christ the Lord, according to His received human nature, rests "the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and the fear of the Lord" (Isaiah 11:2). According to His divinity, Christ is the Second Person in the Holy Trinity. And from Him, as also from the Father, the Holy Spirit proceeds. So the Spirit is and remains Christ's and the Father's own Spirit to all eternity, not separated from God's Son. Therefore, as the Church Fathers say, the entire fullness of the Spirit has been communicated by the personal union to Christ according to the flesh, which is personally united with God's Son. This voluntarily shows itself with all its power ‹in, with, and through Christ's human nature›. So ‹Christ according to His human nature› not only knows some things and is ignorant of others, but He also can do some things and is unable to do others. Yet even now ‹according to the received human nature›, He knows and can do all things. For on Him the Father poured the Spirit of wisdom and power without measure. So as man, Christ has received all knowledge and all power through this personal union. (paragraphs 72-74)
