a Magnificat (1999), and several masses. This central strand of his life and compositions was marked by the BBC Symphony Orchestra in early 2005, with a survey of his music entitled From Darkness into Light. MacMillan and his wife are lay Dominicans, and he has collaborated with Michael Symmons Roberts, a Catholic poet, and also Rowan Williams, the Archbishop of Canterbury. Perhaps his most political work is Cantos Sagrados (1990), a setting of Latin American poetry by Ariel Dorfman and Ana Maria Mendoza, combining elements of liberation theology with more conventional religious texts. MacMillan has explicitly stated that his aim in writing this work was to emphasise 'a deeper solidarity with the poor of that subcontinent' in the context of political repression. Scottish traditional music has also had a profound musical influence, and is frequently discernible in his works. When the Scottish Parliament was reconvened in 1999 after 292 years, a fanfare composed by MacMillan accompanied the Queen into the chamber. Weeks after the opening ceremony, MacMillan launched a vigorous attack on sectarianism in Scotland, particularly anti-Catholicism, in a speech entitled "Scotland's Shame". His Mass of 2000 was commissioned by Westminster Cathedral and contains sections which the congregation may join in singing. Similarly, the St Anne's Mass and Galloway Mass do not require advanced musicianship, being designed to be taught to a congregation. One of his most important commissions (by the Bishops' Conferences of England & Wales and of Scotland) was to write a new mass setting for choir and congregation to be sung at two of the three masses celebrated by Pope Benedict XVI during his Apostolic and state visit to Great Britain in 2010. First sung at mass at Bellahouston Park, Glasgow, on 16 September it was sung again at the mass and beatification of John Henry Newman at Cofton Park, Birmingham, on 19 September). He was also commissioned to write a setting of the text Tu es Petrus (Matthew 16:18) for the Pope's entry at mass at Westminster Cathedral on 18 September. BBC Radio Three broadcast in 2020-2021 Faith in Music, Macmillan's examination of religious faith in the work of seven composers from Thomas Tallis to Leonard Bernstein. Appointments and collaborations MacMillan was composer and conductor with the BBC Philharmonic from 2000 to 2009, following which he took up a position as principal guest conductor with the Netherlands Radio Chamber Philharmonic.
