From Scottland on Sunday:
A devout Catholic, MacMillan uses an article in a religious magazine this weekend to confess his despair of the "screaming microphones" and "incompetently strummed guitars and cringe-making, smiley, cheesy foil groups" which fill churches every Sunday.
He reserves particular venom for two well-known modern hymns, 'Bind Us Together, Lord' and 'Make Me a Channel Of Your Peace', the latter having even been recorded to popular acclaim by Irish singer Daniel O'Donnell.
MacMillan says the hymns amount to "cultural vandalism" and that a backlash against such groups is growing, with more church-goers demanding a return to the traditional music which filled churches before reforms of the 1960s.
He declared: "The church has simply aped the secular West's obsession with 'accessibility', 'inclusiveness', 'democracy' and 'anti-elitism'. The effect of this on liturgy has been a triumph of bad taste and banality and an apparent vacating of the sacred spaces of any palpable sense of the presence of God."
