I taught recently the 4th graders in school during their religion class about the liturgical season. We spent, of course, a decent amount of time on Advent. Why purple for Advent (and Lent as well)? (My brother-in-law, who is from Minnesota and is a Vikings fan will love this post.)
Purple, a fusion of red and blue, is an interesting color. Blue symbolizes calm, steadfastness, and stability. Think of a deep blue sky or sea. Red, on the other hand, symbolizes passion, energy, and movement. Think of fire. Purple combines the steadiness of blue and the fervor of red. In Advent we are called to be focused, recollected, and somewhat solemn as we prepare for our Lord's coming into our lives at Christmas. But we are also called to be alert and excited—and for the same reasons.
The segment from Isaiah (Is 40:1-5, 9-11) in our first reading has this mix of emotions. “Comfort, give comfort to my people,” we hear in the opening line. “Speak tenderly to Jerusalem,” continues the prophet. This is quite blue.
But it turns red quickly. “A voice cries out...cry out at the top of your voice.”
