In preparation for the Feast of the Most Holy Trinity on June 15, and perhaps throughout the month of June, there will be excerpts from the Roman Catechism of the Council of Trent provided for your reflection.
The Trinity Of Persons In God
The Christian faith, therefore, believes and professes, as is declared in the Nicene Creed in confirmation of this truth, that God in His Nature, Substance and Essence is one. But soaring still higher, it so understands Him to be one that it adores unity in trinity and trinity in unity. Of this mystery we now proceed to speak, as it comes next in order in the Creed.
As God is called Father for more reasons than one, we must first determine the more appropriate sense in which the word is used in the present instance.
God Is Called Father Because He Is Creator And Ruler
Even some on whose darkness the light of faith never shone conceived God to be an eternal substance from whom all things have their beginning, and by whose Providence they are governed and preserved in their order and state of existence. Since, therefore, he to whom a family owes its origin and by whose wisdom derived from human things these persons gave the name Father to God, whom they acknowledge to be the Creator and Governor of the universe. The Sacred Scriptures also, when they wish to show that to God must be ascribed the creation of all things, supreme power and admirable Providence, make use of the same name. Thus we read: Is not he thy Father, that hath possessed thee, and made thee and created thee? And: Have we not all one Father? hath not one God created us?
