The newly appointed Archbishop of Canterbury, Justin Welby, the present Bishop of Durham, pledged to examine his own thinking on homosexual marriage "carefully and prayerfully" and spoke out against "exclusion".
If he were a Catholic of course he would know what the Magisterium says. The Magisterium, the teaching authority of the Church, that is the voice of the prayerful meditation of the Church down the ages. As an Anglican Archbishop "careful and prayerful" thinking must always have one of its many ears firmly on the keyhole of the Cabinet Room of No 10, who in turn are plugged into the opinion polls and whatever corner Stonewall and Dave have painted them into.
I remember being given an essay title as a seminarian by our history teacher the great Dr Freddy Broomfield, "The CofE is more a system of ecclesial government than a Church: discuss". Anglican "prayerful thinking" is always going to be different from that of Catholics and the other ancient Churches.
