Sacrament is a word that is used in the western tradition of Christianity to describe a sacred ceremony which is a visible sign of an invisible grace. It is a word used to describe ceremonies of initiation and blessing.
It comes from an old Latin word that means oath, particularly an oath of allegiance. So, inherent in the sacraments is the making of sacred promises and decisions. The grace given is the power to fulfil the promises and decisions made.
In the eastern tradition of Christianity, the word musterion meaning ‘mystery’ was used, rather than sacrament, and this denotes more of an inner experience which sets you apart.
In the scriptures, the word musterion, ‘mystery’, has a broad meaning and refers to the plan and activity of God, as revealed in Christ, for our salvation and wholemaking. It is a word which embraces all the ways God reaches out to us in the world. Any object, person or thing which has somehow brought God and the human soul into contact and reveals this saving love and grace could be called a sacrament.
All of these meanings are inherent in the sacraments and initiation services we practice.
