The change is subtle, as the color of the priests' vestments change from purple to the lighter shade of rose, but the meaning is more pronounced.

After the Diocese of Memphis celebrated the fourth Sunday of Lent, also called Laetare Sunday, the shift was explained.

"The slight change in vestment just this weekend, from purple to rose, reflects the joy of the Liturgy," the diocese said in a Facebook post this week. "The Church wants to remind us that we are beyond the halfway point in our journey of Lent."

Laetare is the Latin word for "rejoice," and with the Resurrection just three weeks away, Laetare Sunday is a time to rejoice. 

"We 'rejoice' because there is something that gives us hope as we head toward Easter," the post said. "What gives us hope is the promise of Easter and its new life."

The rose-colored garments are just one of the symbols of joy churches use to encourage the faithful, a report on NewAdvent.org said. Another includes the placement of flowers on the altar. 

A report on SimplyCatholic.com said the theme of Laetare Sunday comes from Isaiah 66:10-11, which states, "Rejoice, Jerusalem, and all who love her. Be joyful, all who were in mourning; exalt and be satisfied at her consoling breast." 

With the passing of Laetare Sunday, which this year fell on March 27, parishioners celebrate moving past the halfway point of Lent, a report on PillarCatholic.com said. 

"Let's give countless thanks that God is with us," the diocese concluded the post. "Laetare (Rejoice!)."
