This is really what it comes down to: the Church says we must do X and must not do Y and we don’t want to do X and do want to do Y. To some extent we all experience this and there are only two choices: do what we think is right or do what the Church says is right.
The belief that our conscience alone allows us to decide in our favor against the Church is a misunderstanding of what the conscience is and what its limits are. Beyond this, however, is the failure to recognize the full implication of rejecting what the Church teaches, for when we reject a major teaching we also reject the claims the Church makes about herself. (Dei Verbum 10): *"*the task of authentically interpreting the word of God, whether written or handed on, has been entrusted exclusively to the living teaching office of the Church, whose authority is exercised in the name of Jesus Christ." You cannot believe this claim if you believe the Church has misinterpreted the word of God in a significant way, but once you reject this claim you reject the Church’s authority to correctly interpret anything.
(Fides et ratio 7): *"*The knowledge which the Church offers to man has its origin not in any speculation of her own, however sublime, but in the word of God which she has received in faith." Again, if you reject what the Church teaches you cannot believe she has received the word of God but that she is making up morality as she goes along - that her morality is man made and not from God.
What is the appeal of being in a Church whose moral laws cannot be trusted either to be right or to endure beyond the tenure of the latest occupant of the Vatican?
