Williams also said that "it may be that the covenant creates a situation in which there are different levels of relationship between those claiming the name of Anglican. I don’t at all want or relish this, but suspect that, without a major change of heart all round, it may be an unavoidable aspect of limiting the damage we are already doing to ourselves." In such a structure, some churches would be given full membership of the Anglican Communion, while others had a lower-level form of membership, with no more than observer status on some issues. Williams also used his keynote address to issue a profound apology for the way that he had spoken about "exemplary and sacrificial" gay Anglican priests in the past. "There are ways of speaking about the question that seem to ignore these human realities or to undervalue them," he said. "I have been criticised for doing just this, and I am profoundly sorry for the carelessness that could give such an impression."
