I think the issue of complacency is not just restricted to Catholics, I think all faith traditions battle with this. However, I also think that even going through the routine has benefit and shapes you in ways you might not understand yet. Think about the person who is suffering from Alzheimer’s disease. You may walk into the room and they have no idea who you are, or where they are, or what they are doing, but then you start to recite with them the Lord’s Prayer or the Apostle’s Creed and for just that moment they are truly with you alert and aware. They got that way from years of being formed by our worship and liturgy and catechesis in ways that at the time they may have taken for granted, and yet God gave them a gift of faith that has persevered long after their memory and mind has.
