St. Lawrence has existed, since its founding in 1860, as a school for the formation of Catholic high school and college young men interested in pursuing a vocation to ministry in the Catholic Church.
As the understanding of ministry has grown within the Church, the school has historically adjusted its purpose to respond to the various ministerial needs of the Church and society. Underlying the school`s philosophy is the conviction that the primary obligation of all Christians is to witness to gospel values in that life vocation to which God calls them.
Combined with this belief is the additional conviction that such values are not only the path to eternal salvation and union with God for each individual but also the only real remedy for the ills of the human community.
Therefore, the staff of St. Lawrence wishes to promote and foster these values in themselves and in the adolescents who enter into and participate in the life of the community.
The overriding purpose for St. Lawrence`s existence is to promote, foster, and live principles and values announced in the gospel of Jesus Christ and articulated in the Catholic Church.
