CCC 1586 For the bishop, this is first of all a grace of strength (“the governing spirit”: Prayer of Episcopal Consecration in the Latin rite):¹ the grace to guide and defend his Church with strength and prudence as a father and pastor, with gratuitous love for all and a preferential love for the poor, the sick, and the needy. This grace impels him to proclaim the Gospel to all, to be the model for his flock, to go before it on the way of sanctification by identifying himself in the Eucharist with Christ the priest and victim, not fearing to give his life for his sheep:
Father, you know all hearts.
You have chosen your servant for the office of bishop.
May he be a shepherd to your holy flock,
and a high priest blameless in your sight,
ministering to you night and day;
may he always gain the blessing of your favor
and offer the gifts of your holy Church.
Through the Spirit who gives the grace of high priesthood
grant him the power
to forgive sins as you have commanded
to assign ministries as you have decreed
and to loose from every bond by the authority which you
gave to your apostles. May he be pleasing to you by his gentleness and purity of heart,
presenting a fragrant offering to you,
through Jesus Christ, your Son. ..²
