St. Mary Mystical Rose began her lifelong commitment to God and to the Catholic family of Armada on November 20, 1946, when Edward Cardinal Mooney assigned Father Francis Sysol to establish this parish.

During the last month of 1946, three baptisms and a wedding ceremony were performed by Father Sysol. Father proceeded to purchase a parcel of land and accepted a donation of additional land for the construction of the Church building and rectory. The cost of the project was estimated to be $64,000.
