2. About God.

God created the whole world out of nothing, by His Word alone. God can do all that He wishes. God is the highest existence. There is no one nor anything equal to Him anywhere, neither on earth nor in Heaven. We, mankind, cannot fully comprehend Him by our reason. We would know nothing about Him unless He Himself had not revealed it to us. What we know about God has all been revealed to us by God Himself.

When God created the first people, Adam and Eve, He appeared to them in Paradise, revealing Himself to them, revealed how He created the world, and how people must believe in the One True God and fulfill His will. This teaching of God was first passed on orally from generation to generation, but later, at the inspiration of God, it was written down by Moses and by the other prophets in the sacred books.

Finally, the very Son of God, Jesus Christ, appeared on earth and revealed all that mankind needs to know about God. He revealed to mankind a great mystery: God is One but a Trinity in Three Persons. The first Person is God the Father; the second Person is God the Son, the third Person is God the Holy Spirit. These are not three gods but one God in three Persons, the Trinity in one essence and indivisible.

All three Persons have the same divine dignity; there is not a senior one among them nor a junior; as God the Father is true God, so also God the Son is true God, and likewise, the Holy Spirit is true God.

They are different only in that God the Father is not begotten and does not proceed from anyone; God the Son is begotten of God the Father; the Holy Spirit proceeds from God the Father.

Jesus Christ through the revelation of the mystery of the All-holy Trinity taught us not only to worship God truly, but also to love God as all three Persons of the Most-holy Trinity — the Father, Son, and Holy Spirit. All eternally abide with one another in unceasing love and make up one Being. God is all-perfect love.

The great mystery, which God revealed to us concerning Himself, is the mystery of the Holy Trinity, which our weak mind cannot contain or understand.

St. Cyril, the teacher of the Slavs, tried to explain the mystery of the Most-holy Trinity. He said, "Do you see in the heavens the brilliant sphere of the sun and how from it light is begotten and warmth proceeds? God the Father is like the sphere of the sun, without beginning or end. From Him is eternally begotten God the Son, like light from the sun; just as there comes warmth together with light from the sun, the Holy Spirit proceeds. Each one is distinguished separately: the sphere of the sun and the light and the warmth — these are not three suns, but one sun in the heavens. So also, in the Holy Trinity: there are three Persons but God is one and indivisible." Blessed Augustine says: "You see the Trinity if you see love." This means that we can understand the mystery of the Holy Trinity more readily with the heart, that is by love, than with our feeble mind.

The teaching of Jesus Christ, the Son of God, was written down by His disciples in a sacred book, which is called the Gospel. The original word for Gospel is the Greek word Evangelion, which means glad tidings or good news.

The sacred books, gathered together into one book, are called the Bible. This is from Greek word which means "book."

Questions: Can we completely comprehend with our mind what God is and by ourselves learn about Him? Where do we learn about God and how He is the Creator of the world? Who revealed the teaching about God, that He is One but a Trinity in Persons? How are the Persons of the Holy Trinity called? How are They distinguished from One Another? What is the Gospel and what is the Bible?
