We remember Jesus' sacrifice through the sacrament of baptism?
This question is correct up to a point. To be baptized means that we have forsaken our sins and wish to be cleansed of them through the waters of baptism. However we remember Christ when we partake of the Sacrament. If you remember when in the Upper room He said to his Apostles when eating the bread and drinking the water "Do this in remembrance of Me".
