In the season of Lent, it is customary to "bury our Alleluias" and refrain from using "Alleluia" in any of our liturgical responses. Why is that? Well, it might be thought of as a form of fasting; we turn our thoughts from the joy-filled aspects of worship to the deep work of understanding the way of the cross.
Or perhaps it can be likened to planting a seed in the earth; our alleluias lie dormant awaiting the opportunity to burst forth above the soil and rejoice in the new life of Christ. As Helen explained when our "Alleluia" balloon banner was "buried," Lent is a chance for us to spend time with our inner work.
When Easter comes, the Alleluias will make a great return. And, fun fact, did you know that during the octave of Easter (the first eight days of the Easter season), we say a double Alleluia? It's true - because when love wins, you want to shout it out!
