For most of its history, the church has believed that God created everything that exists ex nihilo (out of nothing). The church affirmed this doctrine based primarily on the opening verse of Scripture: “In the beginning, God created the heavens and the earth” (Genesis 1:1). God, who eternally exists as Father, Son, and Holy Spirit, purposed to and did create a universe distinct from himself. Other passages add to the foundation of this belief. For example, the psalmist attributes creation to the word and breath of God: “By the word of the Lord the heavens were made, and by the breath of his mouth all their host. . . . For he spoke, and it came to be; he commanded, and it stood firm” (Psalm 33:6, 9). According to a traditional understanding of this passage, God the Father spoke the universe into existence through the Word (God the Son) and by his Breath (God the Holy Spirit). Creation was a mighty act of the triune God.
