A disclaimer, of sorts...
It's clear that the human mind has people apply one set of conditions to Christianity, and another to, say, medicine or education.
For example: If a mathematician were to abuse children, no one would say, “I told you that math was awful and dangerous!” Similarly, it seems every year the news tells us of a teacher grooming a student, and no one decries education over it. In each case, people know it is the individual's failing, and on him alone the consequences should rightfully fall.
This is not the case with someone who purports to be a Christian or Christian Scientist. If they profess Christianity at all, every flaw and fault in them is linked right to Christianity by the world at large.
In the case of medicine, I know people who have been seeking for a cure for decades, and still are no closer to it. At no point in that journey have they lost hope or thought, “I should try something else because I am just not getting the results.”
Would this person have given that long to Christian Science? Usually after not much time and little real study, people give up and say that it doesn't work. Does anything worth having in life come easy? Much like learning to play a musical instrument, there is a period of learning and practice with little to show for it that needs to happen before things click and results are obvious to yourself and others.
I have proved to myself that Christian Science is real, and provable, and beneficial for a better quality of life — and in the process learned to not hate myself, or feel lost, or suicidal, or scared of the world. One needs only start putting time into dedicated study and practice of this practical Science to start seeing results. And while the study of Christian Science does not bring guilt, it does bring accountability, and often I think people would rather be sick in a socially acceptable way, rather than to follow the Christ and be well. Everyone chooses their own path, and their own level of involvement.
One final thing: If I should mess up, it is not the fault of Christian Science. I take the blame for my own mistakes and missteps on myself as proof that my journey is not complete. There is always more to learn. For every bit of good I have ever received, I give credit to Truth and Love. Error has done nothing good for me, or anyone, and I am grateful to leave it behind as I am able.
