Before we start looking at the uniqueness in each faith, let’s look at the size of the religions. This chart comes from Adherents.com. The website also provides approximate estimates for the many faiths including some that are grouped on this chart.
Each faith that looks at this chart will see errors in their category. The one that stands out to me is the inclusion of the Church of Later Days Saints and the Jehovah’s Witnesses. Both of these are cults that are identified as Christians while not adhering to the Apostle’s Creed. The Apostles’ Creed is the oldest creed, and lies at the basis of most others. Though not, as the long-current legend of its origin affirmed, the direct work of the Apostles, it has its roots in apostolic times, and embodies, with much fidelity, apostolic teaching. The oldest usage of the term “Rule of Faith”, now commonly given to the Scriptures, has reference to this creed. It was the creed that could be appealed to as held by the church in all its great branches, and so as forming the test of catholicity. It was as resting on this creed that the church could be called “catholic and apostolic.”
In spite of the questionable groupings in the faiths, this pie does provide us with an idea of the size of each religion. We will be working with the largest as well as some of the smaller ones, especially one of the oldest ones, Judaism.
Hope you come along for the ride.
