Roman Catholic Worried... Options

As you can tell from the topic title, all this stuff interests me and I'd like to be able to perform some of it, but everything about the Golden Dawn, Hermeticism, and Ceremonial Magick in general tends to freak me out. I'm a Roman Catholic and I'm obscenely worried about my spiritual self getting into some trouble by doing this stuff. Are there any 'Judeo-Christian' roots to these rituals? I mean it doesn't take a lot to notice the archangels and God's names in the rituals, but seeing videos of people using sinister voices and generally acting like they want to be Lucifer's best friend during said rituals is a little worrisome.

If anyone has any advice for me I'd really appreciate it. I want to be closer with my HGA and thereby God by doing a little magick everyday, I desperately want Him to work through me, but what if unwittingly I allow myself to be worked by an entity with less than amiable goals? Etc., etc.

Thanks in advance..

Satanists don't use the LBRP, to my knowledge, and if they do, then they borrowed it from another tradition (i.e. the Golden Dawn, which is all about spiritual growth, theurgy, etc.).

RadiantStar makes an excellent (and eloquent) point in regards to how a neutral thing (like magick or a knife) can be used for many different purposes - it can be a tool for us and a weapon for others. Just look at words, even - they can be used as a tool to communicate or as a verbal weapon.

Intent is a major thing, even moreso with magick.
