Holy Communion, also known as the Sacrament of the Altar blesses those who partake in it with the forgiveness of sins which Chirst's body and blood have won for us on the cross.  Together with forgiveness, God gives all other blessings as well, that is, life and salvation.  The Sacrament of the Altar is a pure, wholesome soothing medicine which aids and quickens our body and soul.  In the Sacrament Christ gives victory over sin and hell and strength for the new life in Him!
