The short version

–
I was a traditional Christian in a rapidly liberalizing denomination (the United Methodist Church).
I ended up as a Lay Delegate representing my church at the Virginia Annual Conference of the UMC for several years. As we debated various social issues, and observed the discussions and votes on those issues from the UMC General Conferences, it occurred to me that God’s moral laws don’t change, so how could we possibly change the moral doctrines of the church by simple majority rule? If something had been wrong for the last 2,000 years of Christian history, and thousands of years of Jewish history before it, who were we to decide it had suddenly become right?
Even though I was fairly confident that my view was the one in accord with Christian Scripture tradition, reason, etc., I knew many people who felt differently and with equal passion to my own. Obviously we couldn’t both be right, but in the UMC it is some average of our positions, determined through a democratic parliamentary procedure, that becomes the ‘law’ of the church. That just didn’t seem right. It seemed more likely to corrupt the church with worldly views than to maintain the church against the world.
So that got me looking for something that wasn’t so transient, something that recognized that majority rule at a conference can’t override the moral teachings of our faith.
At first I looked more toward the more ‘evangelical’ wing of the Methodist/Wesleyan branch of Christianity – Church of the Nazarene, Wesleyan Church, etc. – as well as toward other evangelical-type churches, but the relative lack of central authority didn’t sit well with me. I knew from the Book of Acts that the Church acted under a central authority, and I knew from reason that a non-democratic central authority was the only way to ensure that doctrine didn’t change based on what was popular at the time.
Before too long, it became clear that the only church in the world that had managed to maintain moral clarity through the ages, hold true to the moral teachings of our faith, and operate under a structure suited to maintaining that clarity into the future, was the Catholic Church.
So I started going to Mass (with my wife, who had gone through this whole process with me), and one by one researched my typical Protestant objections to the faith (They worship Mary! They worship statues! They pray to saints, instead of straight to God! They think the Pope is infallible! etc.) and watched them fall away under the patient guidance of the Holy Spirit. Then my wife and I both joined RCIA, went through the process, and entered into full communion with the One, Holy, Catholic, and Apostolic Church!
