What are the names of the sacraments that serve to build up communion in the Church?
Someone who is baptized and confirmed can receive moreover a special mission in the Church in two special sacraments and thus be enlisted in the service of God: Holy Orders and Matrimony.The two sacraments have something in common: They are directed to the good of others. No one is ordained just for himself, and no one enters the married state merely for his own sake. The sacrament of Holy Orders and the sacrament of Matrimony are supposed to build up the People of God; in other words, they are a channel through which God pours out love into the world.
