Do you think believing in "another Christ" and a "co-redeemer" comes down to a difference in color?
I think you don’t understand the reference.
GB - The main point of contention on these threads is the portrayal of Catholic belief as something other than what it is and willful repeated misinterpretation of Catholic Catechism after many corrections.
In Catholicism the term "alter Christi" is used to describe the actions of the priest who, during the mass, acts in the place of Christ in the recreation of the Last Supper. It does not mean, as Dr. Eck states over and over again, that the Priest is an another Christ.
Similarly, the Catechism of the Catholic Church is very, very clear that there is only one mediator, Jesus Christ. It does state that Mary participated in our Salvation by agreeing to birth and raise Jesus.
