There are a huge number of different sects of Christianity, which are normally broken down into broad denominations such as Catholic, Eastern Orthodox, Protestant, Baptist and Anglican. Each of these denominations has its own unique practices and beliefs and can be further broken down into many smaller sub-groups.
Catholicism is the world's largest Christian denomination, with more than 1.2 billion total followers. The two main branches of Catholicism are Latin and Eastern Catholicism, each of which also consists of numerous smaller sects. There are also a number of independent or breakaway Catholic denominations.
Protestantism is considered the second largest major denomination, although there are numerous debates about which denominations should be considered Protestant. For instance, some sources list the Anglican Church as Protestant, while others place it as a separate group that also includes Episcopalian denominations. Overall, Protestantism is the widest ranging major denomination, encompassing groups such as Lutherans, Evangelicals, Methodists, Seventh-Day Adventists and many Reform Churches.
Eastern Orthodox Christianity is another major denomination, which split from the Roman Catholic Church during the Great Schism in the 11th century. This denomination is mostly followed in Russia, Greece and parts of Eastern Europe.
All Christian denominations share at least somewhat similar beliefs and practices, such as the use of the Holy Bible and the belief in Jesus Christ.
