The Diocese of Crookston invites the faithful to participate in their annual Chrism Mass, either in person or via live-stream.

“Join us for the Chrism Mass next Monday at 6:30 p.m.! For those unable to attend, find the livestream at >> https://youtu.be/M-6bsVO4CEo," the diocese posted online. 

The Chrism Mass is traditionally celebrated during Holy Week, according to the U.S. Conference of Catholic Bishops (USCCB). During this Mass, the priest consecrates three oils: the Oil of the Sick, the Oil of the Catechumens and the Chrism, the USCCB explained.

Each of these three oils has a special purpose and they are used accordingly throughout the year, Simply Catholic said. 

The Oil of the Sick is used in the Sacrament of the Anointing of the Sick, during which a priest lays hands on a sick or elderly person, prays for him, and anoints him with oil on his head and hands. 

The Oil of the Catechumens is used to anoint children and adults before their baptism. 

Chrism oil is used to consecrate someone to God, such as during the Sacrament of Confirmation. 

Bishops celebrate a Chrism Mass yearly. During the ceremony, they consecrate enough of each of the three oils for every church in their diocese to use for the year, Simply Catholic said. 

The week between Palm Sunday and Easter is known as Holy Week, Britannica says. This year, it starts Sunday. During Holy Week, Catholics commemorate Judas' betrayal of Jesus, the institution of the Eucharist, Jesus' Passion and crucifixion, his burial and his Resurrection.
