There is no "mind of the Church" independent of the head of the Church: "sensum fidelium" cut off from the Church's leadership is not the sense of faith.

The CDF letter to Curran, which also says he should be removed from a pontifical faculty, does so because "you will no longer be considered suitable nor eligible to exercise the function of a professor of Catholic theology" because "your repeated refusal to accept what the church teaches" on a variety of cited issues (marital indissolubility, contraception, masturbation, homosexual activity, etc.)  CC was not canned for what he might have done as a sideline: he was fired because he was not a Catholic theologian in light of what was contained in his writings (and still writes), which is not Catholic moral theology.
