sermon, especially if an altar call is to take place or if the Sacraments are to be ministered. Evangelical Charismatics may or may not adopt, along with the order of service, Pentecostal practices such as communal, simultaneous prayer in loud voice and glossolalia. Neo-orthodox Conservatives are a group consisting mostly of young ministers of a more academical background, usually in small congregations, who conduct experiments into bringing the IPB toward a more mainline position. They seek to establish a greater catholicity in the Presbyterian worship practice, recovering the use of responsive liturgies, litanies, set forms of intercession and prayer, the observance of the Church Year and use of the Revised Common Lectionary. Their ministers are usually more inclined to wear distinctive garb, such as clerical shirts, Geneva robes or even albs, with stoles. Even though they are fond of traditional hymnody, they usually also employ praise choruses within the context of the service order. Even though the practical implementation of such a project usually faces some resistance and requires a certain degree of compromise, their ideal liturgy is something close to PC (U.S.A.)'s The Service for the Lord's Day. Puritans, the smallest group within the IPB, choose to lead their worship according to the Westminster Directory of Public Worship, instead of the Principles of Liturgy. The order of worship is usually close to the one practiced by Old-school Conservatives, save for three differences: the only music employed in public worship are metric Psalms sung congregationally, a capella; women are not allowed to speak, teach or pray in public services nor Sunday School, except if there be no men present; and no feast of the Church Year is ever observed, not even Christmas and Easter. The IPB has no official liturgy akin to PC (U.S.A.)'s Book of Common Worship. In more solemn occasions, such as weddings and funerals, when ministers of all four liturgical groups find it necessary to use a set liturgy, they usually employ one of three resources: Manual do Culto ("Worship Handbook"), a non-official compilation of orders of service done by Rev. Modesto Carvalhosa de Perestrello to serve as a guide to lay leaders in the early 20th century, published by Cultura Cristã, IPB's publishing branch. Manual Litúrgico ("Liturgical Handbook"), an expansion of Manual do Culto with alternate forms and biblical readings. The Independent Presbyterian Church's Manual do Culto, which is an abbreviated translation of PC (USA)'s 1993
