Mary,
Thank you for your thoughtful comment and please know I completely understand your concerns. In fact I had the very same concerns which prompted me to dig into the issue in search of some answers. I’m wondering, have you actually read the source material on Osiris, Mithras, Dionysius, etc.? I ask because in actuality none of these myth gods share anything that remotely resembles the claims associated Jesus Christ. What your claiming, and what I once claimed as well, is actually one of those things that is prevalent on certain internet sites or in a popular documentaries but is dismissed my all academics and experts in the field. During my pursuit of truth on this subject I wrote a blog on it, I hope you will take the time to go through it.

What’s more, Mary I highly recomend you go to the library and dig in for yourself to the myths. Read them and compare them to the claims of Christianity. I think you will be able to see that indeed Jesus’ path is unique and worth your consideration.

Thank you again for your comment.
