Canterbury said opposition to blessing gay marriages might be seen that way by others.
"The Archbishop of Canterbury has warned the Church of England that refusing to allow blessings for gay married couples could be seen as "akin to racism"."

"Same-sex marriages will begin from the 29 March. Under the Marriage (Same-Sex Couples) Act, the Church of England is explicitly banned from performing the ceremonies, as part of Maria Miller's 'triple lock'."
