Today the Church has entered into the season of Passiontide, which is more ancient then Lent. Now the church begins focusing on the passion of Jesus Christ. Before the reforms of Vatican II, the Fifth Sunday in Lent was called Passion Sunday, that title has now more appropriately been restored to the following Sunday nicknamed “Palm Sunday.” Since the Passion is actually read on that Sunday.
As a sign of mourning the church would cover the crucifixes with purple shrouds this day and they would not be unveiled until the Easter Vigil. Did your Church continue this practice, my pastor read to me for the rubrics for the year that this practice is permissable unless the local bishop says not to.
