Three men are looking at a house. “It is mine,” says one; “because I made it.” “True,” says the second; “but it is also; mine, for I bought it.” “And,” says the third, “it is mine too, ! since I live in it.”
The first thing God taught people - the Jews, the Children of Israel, his “chosen race” - was that there is only one God (Deuteronomy 6, 4). This was not an easy thing for them to; believe, for all the other nations believed in many different gods; in fact it took them many hundreds of years to learn it - to the end of the first part of die Bible, the Old Testament.
Then, when they really believed it, God taught people more about himself. The Son of God, our Lord Jesus Christ, came into the world to redeem and buy it back. He came from God, and himself was God (St. John 10, 30).
And before he went back to heaven, he promised that he would send to every Christian God the Holy Ghost, to live in their souls. The Holy Ghost also came from God, and himself was God.
So, in the New Testament, people learned that, although there is only one God, yet in the one God are three Persons - the Father, the Son, the Holy Ghost. (St. Matthew 3, 16 and 17: the Father speaks from heaven, the Son is baptised in the river by St. John Baptist, the Holy Ghost descends upon him in the form of a dove.
This is called The Mystery of the Holy Trinity (a “mystery,” in Greek, is “something we cannot understand”; “trinity,” from two Latin words, means “three in one”). You remember that I told you (16) that, although we must believe all the articles of the Christian Faith, we are not asked to understand them. This is one of them: that God is One, yet three Persons.
You are like that house. You belong to God the Father, who made you; to God the Son, who bought you; to God the Holy Ghost, who lives in you. God is always all round you, like a triangle whose sides are equal (equilateral).
So to-day’s picture is of me and the Holy Trinity.
