A key belief of almost all Christians is the belief in the Trinity - Father, Son and Holy Spirit, who were all present at the creation of the world and who each take on different roles.

Christianity has many different branches, called denominations. They share many of the same key beliefs, and the majority consider the Bible to be a sacred text.

Christian practices are varied and many of them, such as praying, fit into daily life easily. However, there are other practices that may happen only once in a lifetime, such as visiting a pilgrimage site.
