Every Sunday, then, is a "little Easter." Every Sunday is Christ's feast day. This is why the Sundays during Lent are excluded from the forty days of penance; and why saints' feast days are not ordinarily celebrated on Sunday. All Catholics are seriously obliged to participate in the Church's celebration of Mass on Sundays.
We welcome you home. Find a church near you that is having a “Catholics Can Come Home” class. I know the one at our church starts this next week!
