The Church thus confesses that Jesus is inseparably true God and true man. He is truly the Son of God who, without ceaSing to be God and Lord, Became a man and our brother: "What he was, he Remained and what he was not, he assumed", sings the Roman Liturgy. 95 and the liturgy of St. John Chrysostom proclaims and sings: "O only-begotten Son and Word of God, immortal being, you who deigned for our Salvation to become incarnate of the holy Mother of God and ever-Virgin Mary, you who without change became man and were crucified, O Christ our God, you who by your death have crushed death, you who are one of the Holy Trinity, glorified with the Father and the Holy Spirit, save us!" 96
