A life that is "given''
"Christ's self-giving, which has its origin in the Trinitarian life of the God who is Love, reaches its culmination in the sacrifice of the Cross, sacramentally anticipated in the Last Supper.
"It is impossible to repeat the words of consecration without feeling oneself caught up in this spiritual movement. In a certain sense, when he says the words: 'take and eat,' the priest must learn to apply them also to himself, and to speak them with truth and generosity.
"If he is able to offer himself as a gift, placing himself at the disposal of the community and at the service of anyone in need, his life takes on its true meaning.
"This is exactly what Jesus expected of his apostles, as the Evangelist John emphasizes in his account of the washing of the feet. It is also what the People of God expect of a priest.
"If we think about it more fully, the priest's promise of obedience, which he made on the day of Ordination and is asked to renew at the Chrism Mass, is illuminated by this relationship with the Eucharist.
"Obeying out of love, sacrificing even a certain legitimate freedom when the authoritative discernment of the Bishop so requires, the priest lives out in his own flesh that 'take and eat' with which Christ, in the Last Supper, gave himself to the Church."
