Since the House of Bishops can no longer be trusted to care for all, the implication in Bishop Harries' remark is that they are no longer Christian. You can listen to his interview here. A strong advocate of blessing civil partnerships in church he was rather coy about discussing the current controversy of gay marriages in church saying, "there is a prior and more important step and that is actually warmly to welcome civil partnerships and offer a blessing for them. That is what I think the church could do and what it should do".
Bishop Harries continues to push the liberal strategy of change by stealth while denying traditionalists what they were promised, an honoured place in the church. If the bishops want to restore trust in themselves they must show due contrition and make proper provision acceptable to orthodox Christians in their care.
