The Order of the Most Holy Trinity, also known as the Trinitarians, is a Catholic religious order founded in 1198 by Saint John of Matha and Saint Felix of Valois. The order was established to rescue Christian captives from Muslim captivity and to promote the Christian faith. Members of the order take vows of poverty, chastity, and obedience, and they are dedicated to the service of the poor and the marginalized. The Trinitarians are recognized for their distinctive white and blue habit, symbolizing their devotion to the Holy Trinity. Over the centuries, they have expanded their mission to include education, pastoral care, and social justice initiatives. The order has a presence in various countries, continuing its commitment to serving those in need.
