However , whatever else they might disagree about , Christians are at least united in believing that Jesus has a unique significance . The term " Christian " is also used adjectivally to describe anything associated with Christianity, or in a proverbial sense "all that is noble, and good, and Christ-like. It is also used as a label to identify people who associate with the cultural aspects of Christianity, irrespective of personal religious beliefs or practices.
Nowadays, there are many popular forms and denominations of Christianity beside Roman Catholicism. Although the Catholic Church continues to teach that it alone has carried on the true tradition of the apostolic church and follows the holy curriculum of the Christ. The Second Vatican Council declared all other Christians who follows any other Christian denominations which are also called " Baptized Christians " to be in a certain , although imperfect , communion with the Catholic Church . So to be a Christian today means to be a certain kind of Christian: one with beliefs , practices and traditions that differ from other denominations like Protestantism , Anglicanism , Eastern Orthodox and others from modern Christianity
