A sacrament is a visible sign of an invisible grace. The definition is classical, yet the practice is older than the definition. Water, bread, wine, oil, and the laying on of hands become the ordinary means by which the church believes God acts.

Catholic and Orthodox traditions recognize seven sacraments: baptism, confirmation or chrismation, Eucharist, penance, anointing of the sick, holy orders, and marriage. Most Protestant traditions retain two—baptism and the Lord’s Supper—as the rites clearly instituted by Christ himself. In every case the material element is not magic; it is the appointed vehicle of a promise. Baptismal water does not merely symbolize cleansing; it is the place where cleansing is pledged and given. Bread and wine do not merely remind; they are the communion in the body and blood of Christ.

The Reformers argued over the precise mode of Christ’s presence in the Eucharist and over the necessity of certain rites. Those debates still shape denominational boundaries. Yet across the divisions the underlying conviction persists: God meets human beings through tangible, shared actions rather than through purely private insight.

A sacrament therefore binds the spiritual to the bodily and the individual to the community. It is grace made available in a form that can be seen, touched, and tasted.
