Others object to this distinction, arguing that this terminology obscures the universality of public worship as a religious phenomenon.[4] Thus, even the open or waiting worship of Quakers is liturgical, since the waiting itself until the Holy Spirit moves individuals to speak is a prescribed form of Quaker worship, sometimes referred to as "the liturgy of silence".[5] Typically in Christianity, however, the term "the liturgy" normally refers to a standardised order of events observed during a religious service, be it a sacramental service or a service of public prayer; usually the former is the referent. In the ancient tradition, sacramental liturgy especially is the participation of the people in the work of God, which is primarily the saving work of Jesus Christ; in this liturgy, Christ continues the work of redemption.[6]
