Today we celebrate the Solemnity of the Most Holy Trinity, the central mystery of our Christian faith. The Trinity shows us that God is not distant, but a communion of love inviting us in. Glory be to the Father, and to the Son, and to the Holy Spirit. #HolyTrinity

Trinity Sunday History

The celebration spread through Western Europe and was officially adopted by the Catholic Church in the 14th century. For Canadian Christians, Trinity Sunday represents an opportunity to reflect on the importance of unity and cooperation, considering the multicultural and multilingual diversity in the country.
