For Christians, most of us were born into a Catholic, Eastern Orthodox and other Christian denominations. There are far more people who identify as Baptists and “mainstream” Protestant [Anglican-Episcopal, Methodist, Lutheran, Calvinist-Reformed] than there are Eastern Orthodox globally and in the US. The Roman Catholic is still the largest single faith community in the US, and within Christianity globally. Evangelicals are a large body, especially in the US, and growing in Latin America and Africa, but harder to put hard “boundaries” around. Most Baptists are evangelical, and there are Evangelical Lutherans whom most evangelicals wouldn’t acknowledge as evangelical. Then there are the Pentecostal or charismatic churches, which believe that all of the spiritual gifts manifested in the 1st century church still regularly manifest in true churches today – including healing, prophecy, speaking in tongues, etc. Many people lump Baptists, Evangelicals, and Charismatics in with the three main groups of “mainstream” Protestants as all being Protestants, but while they all do share some beliefs, they are as different from each other in practice and theology as Catholics, Orthodox, and Anglican-Episcopal are from each other. Then there are even more “unusual denominations” like the Seventh-Day Adventists.
