Switzerland. Canton Ticino. Grancia. Church «San Christoforo». Don Gerald Chukwudi Ani (L) and Don Stanley Orazurike (R) are both catholic priests from Nigeria (Africa). They are celebrating the holy Mass of the Lord's Supper, also known as A Service of Worship for Maundy Thursday, which is a Holy Week service celebrated on the evening of Maundy Thursday.It inaugurates the Easter Triduum and commemorates the Last Supper of Jesus with his disciples, more explicitly than other celebrations of the Mass. The Mass stresses three aspects of that event: "the institution of the Eucharist, the institution of the ministerial priesthood, and the commandment of brotherly love that Jesus gave after washing the feet of his disciples. Easter Triduum is the period of three days that begins with the liturgy on the evening of Maundy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. Sacramental bread (Latin: hostia, Italian: ostia), sometimes called altar bread, Communion bread, the Lamb or simply the host, is the bread or wafer used in the Christian ritual of the Eucharist. Eastern and Western traditions both require that it be made from wheat. Transubstantiation is, according to the teachings of the Roman Catholic Church, the change of substance or essence by which the bread and wine offered in the sacrifice of the sacrament of the Eucharist during the Mass, become, in reality, the body and blood of Jesus Christ. An altar server is a lay assistant to a member of the clergy during a Christian liturgy. A young male altar server is commonly called an altar boy. 29.03.2018 © 2018 Didier Ruef
