(1Thes 1, 8-10) You turned to serve the living, true God

[8] For from you the word of the Lord has sounded forth not only in Macedonia and (in) Achaia, but in every place your faith in God has gone forth, so that we have no need to say anything. [9] For they themselves openly declare about us what sort of reception we had among you, and how you turned to God from idols to serve the living and true God [10] and to await his Son from heaven, whom he raised from (the) dead, Jesus, who delivers us from the coming wrath.

(CCC 198) Our profession of faith begins with God, for God is the First and the Last (Cf. Isa 44:6). The beginning and the end of everything. The Credo begins with God the Father, for the Father is the first divine person of the Most Holy Trinity; our Creed begins with the creation of heaven and earth, for creation is the beginning and the foundation of all God's works. (CCC 200) These are the words with which the Niceno-Constantinopolitan Creed begins. The confession of God's oneness, which has its roots in the divine revelation of the Old Covenant, is inseparable from the profession of God's existence and is equally fundamental. God is unique; there is only one God: "The Christian faith confesses that God is one in nature, substance and essence" (Roman Catechism, I, 2, 2). (CCC 202) Jesus himself affirms that God is "the one Lord" whom you must love "with all your heart, and with all your soul, and with all your mind, and with all your strength" (Mk 12:29-30). At the same time Jesus gives us to understand that he himself is "the Lord" (Cf. Mk 12:35-37). To confess that Jesus is Lord is distinctive of Christian faith. This is not contrary to belief in the One God. Nor does believing in the Holy Spirit as "Lord and giver of life" introduce any division into the One God: We firmly believe and confess without reservation that there is only one true God, eternal infinite (immensus) and unchangeable, incomprehensible, almighty and ineffable, the Father and the Son and the Holy Spirit; three persons indeed, but one essence, substance or nature entirely simple (Lateran Council IV: DS 800).
