I love music. Something about it elevates our words and stirs our hearts. When are angels are worshipping along with us at Mass (and they are!), I assume they must also sing along with our hymns. (After all, they're arranged in choirs, hm?) The sound of that, heard from Heaven, must be magnificent.
Through Advent, I'll be exploring the meaning of several timely hymns. The USCCB recommended a number of them on their Lessons and Hymns page. We should always strive to really understand the words we pray at Mass - and the songs we sing.
