Depends on how you defines "largest"
Physically, the one in Vatican could be one of the largest.
In terms of power, other than the Vatican, the next 2 largest "Catholic Church" is actually XXX Bank and XXX Government.
XXX Bank - the clue lies in the symbol of the bank. Look out for the symbol "House of Christ" and you will know which bank is it.
The Catholic is one of the richest organisation in World history from their power to determines heirs of Kings in Europe for centuries, getting a portion of spoils from raiders of North, South, Central America, Africa, Asia (Gold, minerals, artifacts, slavery) and donations. Now you know why some Banks simply refuse to go bankrupt...
XXX Government and its illegal arm - This is a bit too sensitive. Well, they simply refuse to go bankrupt too!
The Basilica of the Immaculate Conception in Washington, D.C. is the largest Catholic Church in the United States - of any name, and one of the ten largest Catholic Churches in the world, certainly the largest under the name of the Immaculate Conception.
The Roman Catholic Church is the largest followed by the United Methodist and Lutheran Churches.
The largest Catholic church in Washington, D.C., is the Basilica of the National Shrine of the Immaculate Conception. This prominent basilica is renowned for its stunning architecture, beautiful mosaics, and significant size, making it one of the largest churches in the United States. It serves as a major pilgrimage site and a center for Catholic worship and events.
No. Catholic Churches, just like many other in the United States, are classified as non-profit organizations. The US Government or any state government can not tax their property or income.
The largest religion is the Roman Catholic Church. The Protestants are small as they are everywhere in New England. The largest Protestant denominations are the United Church of Christ and the Episcopal churches.
The United States Conference of Catholic Bishops uses the Mexican Lectionary in the United States, to the best of my knowledge this is the only lectionary which is approved for use in Catholic Churches in the United States who have a Spanish Mass. This lectionary uses a Spanish-language translation of the Bible called "Biblia de América." This is the Bible translation approved by the Mexican bishops and it is available for sale in the US under that title.
Because at its core The Church is a business. So to protect certain assets and tax deductions, the Catholic church is a corporation. Many Protestant churches and synagogues are also incorporated.
At 63.6% they have the largest Roman Catholic population in the United States.
In the United States of America, there are a number of different religious denominations, but the largest church is the Catholic Church, with over 68 million members.
Protestant churches are just that: protestant, not Catholic. There are currently (2014) over 40,000 denominations in the United States, so different from each other that there is no way to compare them, except in that all of them are not Catholic.
Protestant and Catholic
Catholic churches almost never use the label "Church of Christ," even though that is what they are. They avoid using this term only so as to avoid being confused with other denominations and communities of that or similar name already in existence, such as Churches of Christ; Independent Churches of Christ; International Churches of Christ; United Churches of Christ; United Churches of Christ, Congregational; Churches of Christ, Scientist; and Church of Christ, Instrumental. Catholic churces almost always have the word Catholic in their name.
