Why Jesus is the only mediator between God and man?

This word is reserved for the sacramental act which integrates a man into the order of bishops, presbyters, or deacons.

Ordination confers a gift of the Holy Spirit that permits the exercise of a "sacred power" (sacra potestas) which can come only from Christ himself through his Church.

Ordination is also called consecratio, for it is a setting apart and an investiture by Christ himself for his Church.

No one has a right to receive the sacrament of Holy Orders. Indeed no one claims this office for himself; he is called to it by God.

The matter of the Sacrament of Holy Order is the Bishop’s imposition of hands on the head of the ordained candidate and the consecratory prayer.

The minster of the Sacrament of Holy Orders is a priest.

The form of the Sacrament of Holy Orders is the Bishop's "specific consecratory prayer asking God for the outpouring of the Holy Spirit and his gifts proper to the ministry to which the candidate is being ordained"
