Since it's off-topic, I won't go into detail now, but the moral teachings of Christianity depend on the idea that the judgments of conscience are the product of reason.
It is rather off-topic, so I won't labour the point, however I've explained to you before that this is not quite the case.
Yes, historically the Western Christian tradition has set a high bar upon reason and I don't view this as a negative thing.
However, in it's doctrine on conscience, the church teaches that moral intuitions - or conscience, founded upon unreasoning, consciously inaccessible 'empathy' with others - come first and are born of emotional activation, before ratio or any operations of the rational, logical mind using controlled thought come into play.
As explained by one scholar, Lyons (2009): “conscience is the whole internal conscious process by which first principles of moral right and wrong, learnt intuitively by synderesis [a functional intuitive capacity], are applied to some action now contemplated in order to produce a moral verdict on that action, known as conscientia." (p.479)).
Using your church just as an example, I can accept the idea that conscience might well be the Voice of God but if that's true then the Church is not a moral authority. It should not be offering moral advice that -- when it conflicts with the Voice of God (conscience), it misleads.
Again, as I have noted in our past discussions about this, my church believes doctrinally in the "primacy of conscience":
"...No one ought to act against his own conscience and he should follow his conscience rather than the judgement of the church when he is certain...one ought to suffer any evil rather than sin against conscience..."
- Pope Innocent III's (1198-1216)
- Pope Innocent III's (1198-1216)
But because our understanding of conscience differs from your own in being two-dimensional - generalized intuition subsequently applied in specific situations with the aid of reason - the role of the Magisterium comes in at that stage in the process.
But we are under no illusions that conscience is the Voice of God and thus the individual's ultimate guide, since we believe in natural law.
