III. The Three Degrees of the Sacrament of Holy Orders

From The Catechism of the Catholic Church

1563
“Because it is joined with the episcopal order the office of priests
shares in the authority by which Christ himself builds up and sanctifies and
rules his Body. Hence the priesthood of priests, while presupposing the
sacraments of initiation, is nevertheless conferred by its own particular
sacrament. Through that sacrament priests by the anointing of the Holy Spirit
are signed with a special character and so are configured to Christ the priest
in such a way that they are able to act in the person of Christ the head.”⁴⁵
