I was just wondering, as I think I may have heard this before. When you receive the body & blood of Christ, are you also cleansed of your sin as in baptism? Or is that incorrect?
Confession would also be another baptism....
I think that the phrase "second baptism" has only been applied to confession. I believe it is Saint Symeon the New Theologian who, in one of his precommunion prayers, says that the tears which flow from a contrite and penitent heart wash away the sins at baptism. I'd have to check for the appropriate reference.
Also, remember that baptism, confession, the eucharist are not only for the remission of sins but also for the attainment of everlasting life.
