Sacrament of Holy Communion
The ultimate purpose of Christianity in general and of Catholicism in particular is the Union of God and humanity. Baptism initiates new members into the community of faith on earth and make them heirs of the eternal community in heaven, an eternal stake of being beyond human history where the union with God and with one another begun here on earth reaches its final and perfect fulfillment.

The oil of chrism and the oil of catehumens are blessed at a special chrism Mass, which istraditionally held on Holy Thursday. Oil of chrism, which is olive oil mixed and perfumed with other precious oils, is part of many Catholic rituals. The oil is intended to visibly mark the catechumens with the shining symbol of their faith. Chrism comes from the Greek Chrisma and means 'anointing'. Christ's name means The Anointed One.
The theme of purification in preparation for the sacrament (fasting as purification of the body, confession of sins as purifciation of the conscience) is reflected in wearing clothing that is white - the colour of purity and innocence. White is also the colour of the baptismal garment.
