Please do not allow anecdotal accounts of healings and claims about the veracity of Mary Baker Eddy to color your spiritual judgment, no matter how seemingly compelling.

To know whether a religion is valid, go to it's origins and study the life and claims of it's founder.

Most of all, study the Bible, that Mary Baker Eddy claimed to follow as her guide and see how they differ.

Every Christian has the responsibilty to study the Bible for themselves and not take the word of any teacher or preacher as "God's truth" unless it lines up with Holy Writ. Clearly Mary Baker Eddy's claims and doctrines do not.

Please read and see the vast divergence of Mary Baker Eddy's claims, and what the Bible says about it:
