Jehovah’s Witnesses, Mormons Fastest-Growing ‘Churches’ in U.S.

This article was written by Lillian Kwon for the Christian Post:

The two fastest-growing church bodies in the United States and Canada, according to a newly published report, are ones whose beliefs are known to conflict with traditional Christian teaching. 

Jehovah’s Witnesses and the Church of Jesus Christ of Latter-day Saints, regarded by many Christians as cults, reported the largest membership increases in a year, according to the National Council of Churches’ 2008 Yearbook of American & Canadian Churches.

Although Jehovah’s Witnesses currently rank 25th in size with over 1.06 million members, they reported a 2.25 percent increase in membership since the publication of the 2007 Yearbook. The Church of Jesus Christ of Latter-day Saints – also known as the Mormon church – grew 1.56 percent and is listed by the NCC as the fourth largest “church.”

Notably, however, both Jehovah’s Witnesses and the Mormon church are not accepted within many Christian circles as part of the larger Body of Christ over a number of controversial beliefs that the two religions hold. Identification of the former religion as Christian, among other controversies, is debated largely due to their rejection of the Trinity, which most Christians regard as a fundamental doctrine. Latter-day Saints, meanwhile, are often criticized for their belief in “divine” books of scripture, aside from the Bible, including the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price.

Mormonism was formally listed under “cults and sects” by the Southern Baptist Convention – the largest Protestant denomination in the nation – but was more recently categorized among “newly developed religions” on the North American Mission Board apologetics page.

Other bodies in the newly published top 25 largest churches list that reported membership increases include The Catholic Church with a 0.87 percent increase; the Southern Baptist Convention with a 0.22 percent increase; the African Methodist Episcopal Zion Church with a 0.21 percent rise; and the Assemblies of God with a 0.19 percent growth.

The greatest losses in membership were reported by The Episcopal Church, which dropped 4.15 percent in members, and the Presbyterian Church (U.S.A.), which decreased by 2.36 percent. Both denominations are currently wracked by theological differences and the issue of homosexuality.

American Baptist Churches in the U.S.A. and the Evangelical Lutheran Church in America also experienced large losses in membership, dropping 1.82 percent and 1.58 percent, respectively.

“Some will wish to argue that the slowing growth rate is evidence of an increasing secularization of American postmodern society,” said the Rev. Dr. Eileen W. Lindner, editor of the Yearbook. “While such an explanation will satisfy some, caution in drawing such a conclusion is warranted.”

Lindner also observed that churches are feeling the impact of the lifestyles of Millenials – people in their 20s and 30s – who attend church but resist becoming members.

The United Methodist Church saw a 0.99 percent decrease but the mainline group remains the third largest church body with nearly 8 million members.

Only three of the top 10 largest churches are mainline Protestant churches; three of the top 25 are Pentecostal churches; and six of the top 15 are historic African American churches.

  1. Interesting post…

    1. The Catholic Church – 67,515,016
    2. Southern Baptist Convention – 16,306,246


  2. Lots of interesting stuff in there, wasn’t it?

    That is a big gap between the Catholic’s and the SBC.

    I heard a priest once say, “The second largest denomination in the U.S. is ex-Catholic.”

  3. Wonderful Blog 🙂 thankyou may God use all you write to bless many people 🙂

  4. Thank you, Christian. I hope so too!

  5. 4. The Church of Jesus Christ of Latter-day Saints – 5,779,316
    18. Pentecostal Assemblies of the World, Inc. – 1,500,000
    25. Jehovah’s Witnesses – 1,069,530

    All three of those are anti-Trinitarian. Over 9 million individuals who claim the Bible and don’t hold to a Trinitarian God.

    I wrote a piece on this and the need for Creeds. Many Protestant communions after the reformation simply disgarded these truths and it leads to just these type of misunderstandings and eventually heresy.

    That’s why we profess it weekly. It’s critical to know who God is not just an emotional attachment, but a logical, scriptural & Traditional one that has stood up to the false concepts of century after century.

  6. Wow! That means that 8,348,846 who call themselves Christian, don’t hold to this tenet of the faith. Unbelievable!

    I knew that the Mormans and the J.W.’s didn’t, but I didn’t know that the Pentecostal Assemblies of the World, Inc. didn’t.

    I’ll say it again…..unbelievable!

    Yes, I read your article and I found it very informative!

    We need to earnestly pray for our seperated brothers and sisters: to keep them from heresy, to deliver them from heresy and to bring them home. Amen.

  7. Interesting post Tim. Maybe the Mormons and the CJCLS’s are being more zealous in spreading their message. They are knocking on my door every week. Where do the non-denominationals like myself fit into the picture? Did I miss something in the list?

    Organized religion is dying in America as it has died in Europe. Vacuous spirituality is the name of the game now. You can’t forget the rise in Islam either.

  8. peak9,
    I’m not sure why the non-denominationals aren’t on the list. It may be because they don’t have a central office since each is so different.

    Yes, we need to pray for the churches of America, for strength and life!
