On the feasts of the Lord, when the faithful receive the Body of the Son, they proclaim to one another the Good News that the first fruits of life have been given, as when the angel said to Mary Magdalene, "Christ is risen!" Now too are life and resurrection conferred on whoever receives Christ. 225
Catechism number 1397
The Eucharist commits us to the poor. To receive in truth the Body and Blood of Christ given up for us, we must recognize Christ in the poorest, his brethren:
You have tasted the Blood of the Lord, yet you do not recognize your brother,.... You dishonor this table when you do not judge worthy of sharing your food someone judged worthy to take part in this meal.... God freed you from all your sins and invited you here, but you have not become more merciful.233
