The BBC has learned that the Church of England is to end the moratorium on gay clergy becoming bishops.The move has been denounced by traditionalist evangelicals as divisive. Here’s Robert Piggott.The bitter dispute about whether the gay-cleric Jeffrey John could take up an appointment as bishop of Reading in 2003 led to a steadily deepening rift in the Church of England.Given the tension surrounding the issue of sexuality, the church’s decision to allow men in civil partnerships to become bishops represents a major concession and one with considerable symbolic significance.The church has already agreed to allow people in civil partnerships to become priests provided they promised that they would remain celibate and repent for active homosexuality in the past.Those conditions are now to be extended to clergies becoming bishops.
