A note on magic...
Most people reading this have probably noticed the absence of anything magic.
This absence is quite intentional, and of it I would like to say a couple of things.
First of all, magic is sin. It's that simple.
But, you may say, playing a character who uses magic does not mean that the player is tracing runes in the air, drawing chalk circles, and so on.
If you mean in the hands, granted. But there is something more to say.
One of the themes in the Sermon on the Mount is that purity belongs not only in the hands, but is to penetrate to the heart. Listen to how this precept is applied to sexual purity: "You have heard that it was said, 'You shall not commit adultery.' But I say to you that anyone who looks at a woman lustfully has already committed adultery with her in his heart."
That is to say, sin does not begin with the full act of sexual intercourse (outside of marriage); it is sinful to use the imagination to commit adultery in the heart — and a man who so much as casts one glance in lust has already done so.
The application to magic means that sin does not begin with chanting the words in a spellbook; it is wrong to use the imagination to use magic in the heart... and, just as lust does not begin after spending several minutes imagining every last instant and detail of foreplay and intercourse, pretending to use magic does not begin after imagining every last detail of casting a spell.
Role playing games provide a way to pretend, to use the imagination to become the great explorer who voyages into the unknown, the romantic bard whose tales spin beauty and wonder. Nobody wants to play a scullery maid or a cobbler
