More recently, in 2001, the ACC established full communion with the Evangelical Lutheran Church in Canada (ELCIC). In 2019 this was broadened to include full communion among the ACC, the Episcopal Church, the ELCIC, and the Evangelical Lutheran Church in America. Contrary to the practice in Roman Catholic, Eastern Orthodox and Oriental Orthodox communions, all baptized Christians are welcome to receive Holy Communion in Canadian Anglican churches, in accordance with the resolution in favour of open communion at the 1968 Lambeth Conference. Through the Anglican Communion, the ACC is also in full communion with the churches of the Old Catholic Utrecht Union, the Mar Thoma Church, and the Philippine Independent Church. Unlike the Anglican Churches of the British Isles, it is not a signatory to the Porvoo Agreement which established full communion between those bodies and a number of European Lutheran churches. Liturgy and service books In 1918 and 1962 the ACC produced successive authoritative Canadian prayer books, substantially based on the 1662 English Book of Common Prayer (BCP); both were conservative revisions consisting largely of minor editorial emendations of archaic diction. The 1962 prayer book is still in regular use throughout the ACC, and has been translated into a number of languages. The French translation, Le Recueil des Prières de la Communauté Chrétienne, was published in 1967. In 1985 the Book of Alternative Services (BAS) was issued, officially not designated to supersede but to be used alongside the 1962 prayer book. It is a more thoroughgoing modernizing of Canadian Anglican liturgies, containing considerable borrowings from Lutheran, Church of England, American Episcopal and post-Second Vatican Council Roman Rite Catholic service books; it was received with general enthusiasm and in practice has largely supplanted the Book of Common Prayer, although the BCP remains the official Liturgy of the Church in Canada. The preference for the BAS among many parishes and clergy has been countered by the founding of the Prayer Book Society of Canada, which seeks "to promote the understanding and use of the BCP as a spiritual system of nurture for life in Christ". The tension between adherents of the BCP and advocates of the BAS has contributed to a sense of disaffection within the Church. There have been increasing calls for revision of the Book of Alternative Services. Those who use the BAS have cited various shortcomings as it ages and newer liturgies are produced elsewhere in the Communion.
