The Fathers of the Church included in the Creed the most important truths of the faith taught in the Gospels. Here, in the first and second verses of the Creed, they stated the dogmatic truths about God’s Essence and the Creation of the world. Through Divine Revelation, the Holy Church teaches us to believe in the One God (Deut. 6:4; 1 Tim. 1:17) in Three Persons, Who in the Holy Scriptures are called God the Father, God the Son, and God the Holy Spirit (Matt. 28:19). God the Father is ungenerated and does not proceed from another Person. God the Son is pre-eternally generated by the Father. God the Holy Spirit pre-eternally proceeds from the Father. Nonetheless, all Three Persons of the Holy Trinity are equal in Divinity. The Triune God is The One Who IS (Ex. 3:14). He is Pre-eternal (Is. 41:4; Ps. 89:2), Infinite (Luke 1:33; Ps. 102:27), Everywhere-present (Omnipresent) (Jer. 23:24), All-Wise (Rom. 11:33), All-Knowing (Omniscient) (1 John 3:20), All-Good (Ps. 145:9), All-Righteous (Ps. 145:17), All-Holy (1 Sam. 2:2), and Almighty (Ps. 115:3).
By His Omnipotent Word He brought into being from non-being both the invisible and the visible world (Gen. 1:1). In the first place He created the Kingdom of His eternal glory, giving life to the most pure spirits, the angels (Job 38:6,7). At first all the angels were holy. Some of them, firmly established in holiness, love and striving after goodness, glorify God continuously (Ps. 103:20; Is. 6:3), and carry out God’s commandments. Each Christian believer is given a Guardian Angel at Baptism. Other angels, who did not stand firm in goodness, sinned before God (Jude 1:6) and, remaining in evil, strive to subjugate men, too, to sin (2 Thess. 2:9), in order to drag them down to the same fate which they themselves suffer (Matt. 25:41).The leader of the fallen angels is called the Devil or Satan (The Adversary; John 8:44).
After He had created the incorporeal beings, the Triune God with His Words Let there be… created the whole visible world out of nothing (ex-nihilo) in six days that is, all the host of heaven, the earth on which we live and all that surrounds the earth and finished His work of creation by creating man (Gen. 1:3-28), from whom proceeded the whole human race (Acts 17:26). The first man, created sinless by God’s grace (Eccles. 7:29), was not only like unto the angels of God, but he was also made in the Image and Likeness of God (Gen. 1:26) from the moment of his creation that is to say, he possessed pure wisdom (Gen. 2:20,23), his will was directed towards doing good (Eph. 4:24) and his heart in the righteousness and holiness of truth burned with pure love for the One God, while his conscience was untroubled and at peace. When our first parents were like this, all the creatures which surrounded them were submissive and served them (Gen. 1:26), and the very place of their habitation was called Paradise (Gen. 2:8). The first man kept God’s commandment and lived in constant joy and blessedness.
