<P> The motto of the Church of Scotland is nec tamen consumebatur (Latin) --' Yet it was not consumed', an allusion to Exodus 3: 2 and the Burning Bush . </P> <P> The basis of faith for the Church of Scotland is the Word of God, which it views as being' contained in the Scriptures of the Old and New Testament' . Its principal subordinate standard is The Westminster Confession of Faith (1647), although here liberty of opinion is granted on those matters' which do not enter into the substance of the faith' (Art . 2 and 5). There is no official document in which substantial matters and insubstantial ones are clearly demarcated . </P> <P> The Church of Scotland has no compulsory prayer book, although it does have a hymn book (the 4th edition was published in 2005). Its Book of Common Order contains recommendations for public worship, which are usually followed fairly closely in the case of sacraments and ordinances . Preaching is the central focus of most services . Traditionally, Scots worship centred on the singing of metrical psalms and paraphrases, but for generations these have been supplemented with Christian music of all types . The typical Church of Scotland service lasts about an hour, and has been characterised jokingly as a hymn - prayer sandwich, in which everything leads up to a climax in a 15 - minute sermon near the end . There is normally no sung or responsive liturgy, but worship is the responsibility of the minister in each parish, and the style of worship can vary and be quite experimental . In recent years, a variety of modern song books have been widely used to appeal more to contemporary trends in music, and elements from alternative liturgies including those of the Iona Community are incorporated in some congregations . Although traditionally worship is conducted by the parish minister, participation and leadership by members who are not ministers in services is becoming more frequent, especially in the Highlands and the Borders . </P> <P> In common with other Protestant denominations, the Church recognises two sacraments: Baptism and Holy Communion (the Lord's Supper). The Church baptises both believing adults and the children of Christian families . Communion in the Church of Scotland today is open to Christians of whatever denomination, without precondition . Communion services are usually taken fairly seriously in the Church; traditionally, a congregation held only three or four per year, although practice now greatly varies between congregations . In some congregations communion is celebrated once a month . </P>
