Ah, that’s the question, isn’t it? How do we know which Spirit is the True Spirit?
Yes…that IS the question.
And how can we know whose reason is really the right one? What evidence is genuine? There are persuasive experts of every religious denomination that can spin stories and explain facts that sound very plausible to someone. The Mormons have healed the sick, cast out demons, and even raised the dead. So have the Catholics.
Or they have alleged to. I can relate experiences as an LDS Missionary that would widen your eyes. But, I believe that God led me THRU the LDS Church to be Catholic. Not sure I could have ever been Catholic without first being LDS.
People come up with personal answers to these problems. They know what they feel and understand; you know that your experience in the Catholic Church far exceeds what you had as a member of the LDS Church. It really does. You also find the reasoning of the Catholic apologists and theologians far more satisfying than the Mormon ones, which seem impossibly weak in your estimation.
I know this sounds simplistic, but I look at doctrine. See, there are things that LDS call doctrine that are NOT Biblical. The only way they become Doctrine is because Joseph had an alleged revelation. If it takes the word of a self-proclaimed prophet to make it doctrine that differs from the Bible, then that causes HUGE questions. It also makes it impossible to truly debate a Mormon because when they start spouting new and odd doctrine, they just say, “A Prophet said it”.
You feel like you have awakened from a dream, maybe an unpleasant one. Where once you slept, now you are awake; and you can tell the difference just as you know you awaken each morning. It is night and day; the one so false, and the other so genuine. That is what it is like, at least that is what I gather from those who have been converted and really believe. The content of their belief seems not to matter, of course; whether Catholic, LDS, or what have you. Many of them report the same quality of conviction in their beliefs.
When I came across all those doctrines I was never taught, it was like a weight had suddenly crashed on me. I could not accept them. When I lost my testimony, I was devastated. Yet, when I left the Church, that weight was lifted. 13 years later, when I was led to become Catholic, it was amazing.
I don’t doubt them.
