I studied (as an extra module) Moral Philosophy at Uni, and I'm interested to consider the difference between that and Theological Philosophy. The reason I say this is that the latter (obviously) has to take into account belief and the tenets of a/all religion/s. Thus, 'God'-given rules and regulations can be rather far from what might be termed ethically tenable from a mere, secular moral viewpoint. To give an example, if one is OK about sex between consenting adults of any sexuality not in committed relationships, with adequate protection against STD's etc, this could (depending on ones stance) be seen as ethically unobjectionable. But according to many religions, including Christianity and especially Catholicism, this is not allowed, and seen as a 'sin'. It is this sort of discrepancy between moral and religious ethics with which I have problems. But sexuality isn't the only department of contention. Divorce and remarriage is another example, and having various 'thoughts' of envy, anger, desire etc. Bad thoughts are sins, (as I understand it) but in no way can I defend a religion which tries to modify ones freedom to think!
