My Latin project, since June, has been Expositio in Orationem Dominicam by Saint Thomas Aquinas. This is more or less an extended lecture on the "Our Father" prayer. This is what the first section looks like.
So it says "Father". Note two things: how God is our father, and what we owe to him, because he is Father. So "father" is said, by reason of our special creation, because he created us in his image and likeness, which he did not bestow upon other, lesser creatures. Deuteronomy 32:2 "The one who made and created you is your father". Next, "father" is said by reason of governance. For although God governs all, nevertheless, he rules us like lords and other creatures like servants. Wisdom 14:3, "your providence, Father, governs the whole world" and again, 12:18, "and you arrange us with great reverence." Next, "father" is said by reason of adoption, because he gave other creatures something like a small present, but to us, he gave an inheritance, because we are his children. "But if we are his children, we are also his heirs" (Romans 7:17). The Apostle, Romans 8:15, "We have not accepted a spirit of slavery in fear, but a spirit of adoption of children, by which we cry, 'Abba, father'."
Therefore, we owe God four things. First, honor. Malachi 1, 6: "If I am father, where is my honor?". Honor consists of three things. In giving praise with respect to God. Psalm 49:23 "A sacrifice of praise will honor me." The honor should not be only in the mouth, but also in the heart. Isaiah 29:13, "this people honors me with their lips, but their hearts are far from me." Honor consists of the purity of body in respect to itself. 1 Corinthians 6:20, "Glorify and carry God in your body." Honor also consists of the fair judgment of your neighbors. Psalm 98:4, "the king's honor loves judgment".
Second, we owe God imitation, because he is father. Jeremiah 3:19: "You will call me father, and you will not stop following after me". The imitation of God is carried out in three ways. In love; Ephesians 5:1 "You will be imitators of God, like most dear children, and walk in love", and it is proper for this to be in the heart. In compassion; for love should be with compassion. Luke 6:36, "Therefore, you will be merciful", and it is proper for this to be in works. In perfection; because love and compassion should be perfect. Matthew 5:48, "Be perfect, just as your heavenly father is perfect."
Third, we owe God obedience. Hebrews 12:9, "How much more should we obey the spirit of the father?". And this is done through three things. First, through the Lord; for he is Lord. Exodus 24:7, "We will do all that the Lord has spoken, and we will be obedient". Second, through example; because "the true son is made obedient to the father, even unto death", as is said in Philippians 2. Third, because it is proper; 2 Kings 6:21, "I will play before the Lord who chose me".
Fourth, we owe God patience in punishment. Proverbs 3:11-12: "My child, do not cast aside the discipline of the Lord, nor revolt when you are seized be him. For the Lord seizes whoever he loves, and like a father with a son, he chastises them."
Our. [In Latin, the word "our" comes after "father" in "Our Father", so St. Thomas Aquinas talks about "our" second.] From this, it is shown that we owe our neighbors two things. First, we owe them love, because they are our brothers, for all are children of God. 1 John 4:20, "Whoever does not love his brother, who he sees, how can he love God, who he does not see?". Then, we owe them reverence, because they are children of God. Malachi 2:10, "Is there not one father of all of us? Did not one God create us?". Therefore, why does every one of you hate your brother?". Romans 12:10, "Mutually excelling in honor". And this is because of our fruit, because "he was made the source of eternal health, for all those who are obedient", Hebrews 5:9.
