But we don't become Christ. The weight and shield of Christ's righteousness saves us, and not our own.
There is no "another Christ." Just like there is no "Co-Redeemer" nor Co-Redemptrix."
Solus Christus!

That is correct. We do not become an actual Christ - that is ridiculous. We do believe that the priest, acting in Sacramental fashion, acts as the corporal hands, directed by Christ, in administering the Sacraments.
The priest, beseeching the Holy Spirit to bless us in Baptism; the priest beseeching that Jesus proceeds with the Sacrament of the Eucharist. It really is God alone; we just do as He has directed us.
