The Sacrament of Holy Orders The call to serve the Church in Sacred Orders, that is as a Deacon, Priest, or Bishop, is a call from God. This vocation is also very unique and personal to each individual. Those who feel an inclination to give their life in service of the Church even as a Religious Sister or Brother, or as a lay missionary, should speak to one of the priests of the parish. All parishioners are asked to pray regularly for an increase in the numbers of those who respond to such a call.
