Catholic Ceremony

Bless Water. You touch the material component, one vial of water, and cause it to become holy water. This can be performed during a Mass, but need not be. 

Holy Sacrifice of the Mass. You read a set of prescribed readings from the Lectionary, and then from the Book of the Gospels, give a homily to any other willing participants, pray with and for them. Then you prepare and pray over bread and wine, which then become (without changing appearances) the Body, Blood, Soul, and Divinity of Jesus Christ. You consume them, then distribute them to any of the participants who share the Catholic Faith with you. All masses require the use of a Lectionary, Book of the Gospels, Catholic Missal, a vial of water, and vial of wine, and a loaf of wheat bread.

Funeral Mass. During the Mass, you touch one corpse, and for the next 7 days, the target can't become undead by any means.

Sacrament of Baptism. During the Mass, you touch one humanoid who wishes to be dedicated to your god's service. For the next 7 days, whenever the target makes a saving throw, it can roll a d4 and add the number rolled to the save. A creature can benefit from this rite only once.

Sacrament of Confirmation. During the Mass, you touch any number of willing humanoids. For the next 7 days, whenever the target makes an ability check, it can roll a d4 and add the number rolled to the ability check. A creature can benefit from this rite only once.

Sacrament of Matrimony. During the Mass, you touch two adult humanoids of opposite sex who are willing to be bonded together in marriage. For the next 7 days, each target gains a +2 bonus to AC while they are within 30 feet of each other. A creature can benefit from this rite again only if widowed.
