The school seal is composed of a shield circumscribed by the school’s name and location, St. Joseph’s College, Quezon City, Philippines. At the bottom of the shield is the year the school was founded, 1932. Cutting across the shield is a ribbon bearing the motto: SAPIENTIA, BONITAS, CARITAS (Wisdom, Goodness, and Love).
SAPIENTIA, enlightened knowledge is symbolized by the books over which stands a lighted lamp.
BONITAS, is represented by the Franciscan symbol: cross under which are the crossed hands of Jesus Christ and St. Francis of Assisi.
CARITAS, loving service, is symbolized by the rose. The seal suggests symbolically the school’s patron St. Joseph, with the carpenter’s toolbox and lily. The fleur de lys stands for our Lady of the Immaculate Conception under whose special patronage the school is entrusted.
