13 January - St Hilary of Poitiers

St Hilary is known as a defender of the faith, and wrote some of the greatest theology on the Holy Trinity. He is the patron saint of lawyers, children with disabilities, mothers, and sick people. He also wrote hymns which were the first in the West by a known writer, and one of them, known as the Morning Hymn, is used in the Liturgy of the Hours today.
