A priestIn the Roman Catholic Church, the priest is an unmarried man ordained as a priest by the bishop, which gives him the right to administer the six other sacraments: baptism, confirmation, confession, Eucharist, marriage, and the anointing of the sick., deaconIn the early Christian Church, the deacon was a man or woman ordained to practise Christian mercy (care of the poor, the sick, prisoners, strangers). In the course of history, the ordination of deacon became an ordination that preceded priesthood. Since the Second Vatican Council [1962-1965], the ministry of deacon has revived. Now the 'permanent deacon' is a man, married or not, who in addition to the permanent care of the weak, also has a role in preaching and proclamation. He may also administer two sacraments: baptism and anointing of the sick. or lay person who explains the Bible readings during the celebration of MassThe liturgical celebration in which the Eucharist is central. It consists of two main parts: the Liturgy of the Word and the Liturgy of the Eucharist. The main parts of the Liturgy of the Word are the prayers for mercy, the Bible readings, and the homily. The Liturgy of the Eucharist begins with the offertory, whereby bread and wine are placed on the altar. This is followed by the Eucharistic Prayer, during which the praise of God is sung, and the consecration takes place. Fixed elements are also the praying of the Our Father and a wish for peace, and so one can symbolically sit down at the table with Jesus during Communion. Mass ends with a mission (the Latin missa, from which 'Mass' has been derived): the instruction to go out into the world in the same spirit.. Sometimes a preacher also acts outside of Mass celebrations (and in the past he did so regularly) to clarify certain points of faith and to encourage the churchgoers to a more Christian way of life.
