When the Archbishop of Canterbury supported the Catholic Church in the gay adoption row last week, many were surprised.

Dr Rowan Williams, usually considered a moderniser, was criticised by liberals for asking Tony Blair to exempt Catholic adoption agencies from Government regulations - being introduced in April - which will force all agencies to offer children for adoption to gays.

The Guardian newspaper, in a comment piece, even suggested that the church's moral authority was 'fatally compromised'.Now it has emerged that Dr Williams may have been influenced by his close involvement with a remarkable couple who rescued a boy brutalised by a notorious social services paedophile ring.Horrified by the inference that the Archbishop is homophobic, the couple have spoken for the first time of their friend's 'immeasurable' help as they struggled to save a child driven to despair by abuse while in the care of the London borough of Islington.

And they described how Dr Williams even devoted an entire week's prayers for Liam, the terribly damaged boy they went on to foster.Liam Lucas was just one of the children abused by predatory paedophiles who took advantage of far-Left Islington Council's childcare policies in the Eighties and Nineties, when it pro-actively recruited gay social workers.

Paedophiles exploited its well-intentioned commitment to equal opportunities and soon most of Islington's 12 children's homes had child molesters on the staff who cynically pretended to be ordinary homosexuals. Numerous children and other staff made allegations of abuse, but were branded homophobes and ignored.Liam - now 29, in a permanent relationship and the proud father of year-old Isabella - was even falsely classified as gay by Islington social services, which decided he should be fostered only by single men.

Quaker couple Brian Cairns, 57, and his wife Kate, 56 - who became friends with the future Archbishop when they were students together - fought to foster him instead. The horrors Liam later disclosed eventually helped end a 20-year regime of appalling abuse.
