The Most Holy Trinity is a Mystery of our faith, a mystery not to solve, but to believe in. Three Persons in One God - Father, Son and Holy Spirit. While we cannot fully understand this mystery, we can be confident that the Spirit will guide us to all truth. This week, use today's gospel acclamation in prayer asking for deeper understanding of the mystery of the Trinity: "Glory to the Father, the Son, and the Holy Spirit; to God who is, who was, and who is to come."
