All Liturgical celebrations, especially the celebration of theEucharistic Liturgy, are celebrations of the whole Church. They are not private functions. The Church is the “sacrament of unity: the holy people united and arranged under their bishops. Therefore, liturgical services pertain to the whole Body of the Church”.   (CSL 26)

In the midst of this Body, there are individual ministries who serve all the faithful by executing different functions. These functions are integral and necessary parts for the liturgy to be performed in a dignified and reverend manner, and for respecting the nature, shape, and dynamic of liturgy. These ministries may include:

Priest (Main Celebrant)
Deacon
Altar Servers
Extraordinary Ministers of Holy Communion
Lectors
Ushers
Music Ministers (choir/cantor)
