The following is part of B16’s General Audience series on the Fathers of the Church. Remember, I have a study guide to these talks, available for download here. Excerpts at the end of the post.
Banished to Phrygia in present-day Turkey, Hilary found himself in contact with a religious context totally dominated by Arianism. Here too, his concern as a Pastor impelled him to work strenuously to re-establish the unity of the Church on the basis of right faith as formulated by the Council of Nicea. To this end he began to draft his own best-known and most important dogmatic work:De Trinitate (On the Trinity). Hilary explained in it his personal journey towards knowledge of God and took pains to show that not only in the New Testament but also in many Old Testament passages, in which Christ’s mystery already appears, Scripture clearly testifies to the divinity of the Son and his equality with the Father. To the Arians he insisted on the truth of the names of Father and Son, and developed his entire Trinitarian theology based on the formula of Baptism given to us by the Lord himself: “In the name of the Father and of the Son and of the Holy Spirit”.
The Father and the Son are of the same nature. And although several passages in the New Testament might make one think that the Son was inferior to the Father, Hilary offers precise rules to avoid misleading interpretations: some Scriptural texts speak of Jesus as God, others highlight instead his humanity. Some refer to him in his pre-existence with the Father; others take into consideration his state of emptying of self (kenosis), his descent to death; others, finally, contemplate him in the glory of the Resurrection. In the years of his exile, Hilary also wrote the Book of Synods in which, for his brother Bishops of Gaul, he reproduced confessions of faith and commented on them and on other documents of synods which met in the East in about the middle of the fourth century. Ever adamant in opposing the radical Arians, St Hilary showed a conciliatory spirit to those who agreed to confess that the Son was essentially similar to the Father, seeking of course to lead them to the true faith, according to which there is not only a likeness but a true equality of the Father and of the Son in divinity. This too seems to me to be characteristic: the spirit of reconciliation that seeks to understand those who have not yet arrived and helps them with great theological intelligence to reach full faith in the true divinity of the Lord Jesus Christ.
