The rights of disabled people historically developed from legislation against racism and sexism. Disabled people’s causes have a deep kinship with the struggles of other excluded people.
The recent Employment Tribunal decision against a married gay priest working as an NHS hospital chaplain has set three worrying precedents, as Peter Tatchell, the veteran LGBT rights campaigner, observes:

This decision sets three dangerous precedents: that the Church of England is exempt from the laws prohibiting workplace discrimination; that it is entitled to discriminate against gay clergy who have been lawfully married in a civil ceremony; and that it can lawfully dictate to non-religious institutions, such as the NHS, who they can employ.
This contradicts the principles of the Equality Act 2010.
It gives a green light to Bishops across Britain to witch-hunt married gay clergy.

On Christmas Eve we look to a revolutionary power–a king not just of earthly administration but of all reality who came not to exclude or oppress but to liberate–and came not in a motorcade with motorcycle outriders but in a stable when there was no room anywhere else.
Let us honour and promote Christ’s revolutionary message by honouring and promoting people marginalized by power.
