Religion is not a requirement...Morals have nothing to do with religion
I think morals are very much related to religion. It's true that religion is not a "requirement" for morality, but religion best enables us to comprehend the phenomenon of human morality.
In the form of Christianity, religion explains the origin of morality (a Creator, in whose image we are made); religion provides the source reference for morality (the holy scriptures); religion identifies the moderator of personal moral conduct (conscience, that metaphysical organ that excuses or accuses us to ourselves); and religion grants us the capability to transcend the limitations of an abused, weak, or damaged conscience, bringing it to perfection and keeping it fine-tuned through the process of inward transformation or spiritual rebirth (by operation of the spirit of Christ).
Judeo-Christian theology is
the only reasonable context in which you can begin to grasp the reality of a broad spectrum of moral virtues (mercy, kindness, patience, equity, impartiality, honesty, faithfulness, obedience, and so on) being at least universally comprehended, if not universally displayed, by the human race.
