Answer 2

A sacrament is a Christian rite recognised as of particular importance and significance. There are various views on the existence and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a means by which God enacts his grace. Many denominations, including the Anglican, Catholic, Lutheran, Methodist and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace that has been instituted by Jesus Christ.[1][2][3][4][5] Sacraments signify God's grace in a way that is outwardly observable to the participant.[5]
