Dear Mr Cameron,
"This is the time when, as Christians, we remember the life, sacrifice and living legacy of Christ."
No, it is not. We celebrate as our only hope in life and death, the perfect life, atoning sacrifice, bodily resurrection and current intercession of Jesus Christ before the throne of our Father God.
Please do not patronise us with talk of shared values. Pretending to share values does not even restore society, or reconcile families, never mind restore us to a reconciled relationship with the God of the universe. Jesus Christ did not die and rise again to share a vague feeling of peace to inspire us. While we are powerless to do peace, he came to be our peace, to make peace, and to preach that peace with the Father [Eph 2]. There is no eternal hope in a 'living legacy'. There is sure and certain hope for a broken, rebellious and dead world, in a Man who defeated death and rose as the first-fruits of a new creation, and will return to judge the living and the dead.
