Part I, Chapter II: The Unity and Trinity of God

12. What is meant by the unity of God?
By the unity of God is meant that there is only one God and there cannot be more than one.
13. Why can there be only one God?
There can be only one God, because God is supreme and infinite.
14. What do we mean by the Blessed Trinity?
By the Blessed Trinity we mean that in the one God there are three divine persons, really distinct and equal in all things, the Father, the Son and the Holy Ghost.
15. Is the Father God?
The Father is God and the first person of the Blessed Trinity.
16. Is the Son God?
The Son is God and the second person of the Blessed Trinity.
17. Is the Holy Ghost God?
The Holy Ghost is God and the third person of the Blessed Trinity.
18. Are the three divine persons one and the same God?
The three divine persons are one and the same God, because they have one and the same divine nature.
19. Can we understand how there can be three divine persons in the one God?
We cannot fully understand this truth, because our human minds are limited and therefore cannot fully understand the infinite God (Rom. xi, 33).
20. How do we show our belief in the Blessed Trinity?
We show our belief in the Blessed Trinity especially by making the sign of the Cross.
21. How do we make the sign of the Cross?
We make the sign of the Cross by putting the right hand to the forehead, then under the breast, then to the left and right shoulders, saying: In the name of the Father, and of the Son, and of the Holy Ghost. Amen.
