Confession is one of the seven Holy Sacraments of the Catholic Church that is very vital before taking the Holy Communion during the Holy Mass. Why is it important for us Catholics to confess and receive absolution before we take the Blessed Sacrament? Because we must be in “state of grace” when we received our Lord. “State of Grace” means we are absolved from our sins that we’ve done and our soul is cleansed during the Sacrament of Penance.
