Catechesis: Sacrament of the Altar

For in the first instance, we are born anew through baptism. However, our human flesh and blood, as I have said, have not lost their old skin. There are so many hindrances and attacks of the devil and the world, that we often grow weary and faint and at times even stumble. Therefore the Lord’s Supper is given as a daily food and sustenance so that our faith may be refreshed and strengthened and that it may not succumb in the struggle but become stronger and stronger. For the new life should be one that continually develops and progresses.—LC V:23-25
