The Catholic faith teaches that the priest is another Christ, an alter Christus

And for our scripture reading this Sunday morning, lets turn to Matthew 24:5 in which Jesus said:

"For many shall come in my name, saying 'I am Christ', and shall deceive many".

"And Jesus answering, said to them: You err, not knowing the Scriptures, nor the power of God." Mathhew 22:29

"He that heareth you, heareth me; and he that despiseth you, despiseth me; and he that despiseth me, despiseth him that sent me." Luke 10:16

"As also in all his epistles, speaking in them of these things; in which are certain things hard to be understood, which the unlearned and unstable wrest, as they do also the other scriptures, to their own destruction." 2 Peter 3:16

"And I live, now not I; but Christ liveth in me. And that I live now in the flesh: I live in the faith of the Son of God, who loved me, and delivered himself for me." Galatians 2:20

"According to my expectation and hope; that in nothing I shall be confounded, but with all confidence, as always, so now also shall Christ be magnified in my body, wither it be by life, or by death. For to me, to live is Christ; and to die is gain." Philippians 1:21

'I answer that, As stated above (78, 1,4), such is the dignity of this sacrament that it is performed only as in the person of Christ. Now whoever performs any act in another's stead, must do so by the power bestowed by such a one. But as the power of receiving this sacrament is conceded by Christ to the baptized person, so likewise the power of consecrating this sacrament on Christ's behalf is bestowed upon the priest at his ordination: for thereby he is put upon a level with them to whom the Lord said (Luke 22:19): "Do this for a commemoration of Me." Therefore, it must be said that it belongs to priests to accomplish this sacrament.' St. Thomas Aquinas Summa Theologica
