Baptism is the commencement of our life in the Church. And it is a baptism that makes us missionaries and not ordination or religious life. This is even the theme of this extraordinary month of mission: "baptized and sent". It is not ordained and sent or professed and sent but baptized and sent.
And the sacraments of service (ordination and matrimony) are the sacraments of service to the community in which we are baptized. These are what I call secondary sacraments. They are secondary sacraments because they are built upon the sacraments of initiation. And the sacraments of service are simply the fructification of our baptismal call.
