23 Q. How many persons are there in God? A. In God there are three divine persons really distinct and equal in all things—the Father, the Son, and the Holy Ghost.

"Distinct," not mingled together. We call the first and second persons Father and Son, because the second is begotten by the first person, and not to indicate that there is any difference in their age. We always see in the world that a father is older than his son, so we get the idea perhaps that it is the same in the Holy Trinity. But it is not so. God the Father, and God the Son, and God the Holy Ghost existed from all eternity, and one did not exist before the other. God the Son is just as old as God the Father, and this is another great mystery. Even in nature we see that two things may begin to exist at the same time, and yet one be the cause of the other. You know that fire is the cause of heat; and yet the heat and the fire begin at the same time. Though we cannot understand this mystery of the Father and Son, we must believe it on the authority of God, who teaches it. First, second, and third person in the Blessed Trinity does not mean, therefore, that one person was before the other, or brought into existence by the other.

24 Q. Is the Father God? A. The Father is God and the first Person of the Blessed Trinity.

25 Q. Is the Son God? A. The Son is God and the second Person of the Blessed Trinity.

26 Q. Is the Holy Ghost God? A. The Holy Ghost is God and the third Person of the Blessed Trinity.

27 Q. What do you mean by the Blessed Trinity? A. By the Blessed Trinity I mean one God in three Divine Persons.

*28 Q. Are the three Divine Persons equal in all things? A. The three Divine Persons are equal in all things.

29 Q. Are the three Divine Persons one and the same God? A. The three Divine Persons are one and the same God, having one and the same divine nature and substance.

Though they are one and the same, we sometimes attribute different works to them. For example, works of creation we attribute to God the Father; works of mercy to God the Son; and works of love and sanctification to the Holy Ghost; and you will often find them thus spoken of in pious books; but all such works are done by all the Persons of the Trinity; because such works are the works of God, and there is but one God.

*30 Q. Can we fully understand how the three Divine Persons are one and the same God? A. We cannot fully understand how the three Divine Persons are one and the same God, because this is a mystery.
