I saw that course on gnosticism and it opened up a lot of questions. The possibility that there is an imperfect and possibly somewhat malicious God in control of this world better answers the question of why we live in an imperfect world. And the premise that to know yourself is to know the Supreme God, also known as "The Invisible Virgin Spirit." But when Gnosticism requires us to make a commitment to Gnosticism forever without committing to another religion, otherwise face Eternal damnation is where I draw the line. Similar religions require the same commitment. I'm Catholic. I can study and live a good life iaw what other religions say. And those other religions say i have a chance by following my own religion. But if I switch religions, even with Catholicism, that's the worse thing i can do. So switching to anything else is unthinkable.
But still I find the study of other religions to be truly fascinating. Because "Enquiring minds want to know!"
