The wrong place to address this really, but for the benefit of Giles Fraser (of whom I too have a fairly high opinion), whilst people may self-identify as Christian on any basis as far as I am concerned, as far as his and many churches are concerned, Christians are identified quite specifically by the following text, which the good Canon appears to have conveniently forgotten - unless he is a closet Quaker.

I believe in God, the Father almighty, Creator of heaven and earth, and in Jesus Christ, his only Son, our Lord, who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died and was buried; he descended into hell; on the third day he rose again from the dead; he ascended into heaven, and is seated at the right hand of God the Father almighty; from there he will come to judge the living and the dead. I believe in the Holy Spirit, the holy catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and life everlasting.

Not as vague as all that, don't'cha think?
