Christianity takes its roots in the 1st century and is centered around the person and work of Jesus Christ. Christianity has three main branches of belief and practice: Catholicism, Protestantism, and Eastern Orthodoxy. Christians worship a triune God, professing Jesus Christ as the savior of the world, and believing in the power of the Holy Spirit to sanctify and transform lives. 

The Catholic church has communities around the globe, and its governing center is in Rome, Italy.

The Orthodox church, or the Eastern half of the Christian church, became independent from the Catholic church in 1054 A.D. Orthodox Christians are incredibly diverse, and among the nationalities and cultures represented are Antiochian, Carpatho-Russian, Greek, Romanian, Russian, Serbian, and Ukrainian.

The Protestant church formed in the 16th century, splitting from the Catholic church over disputes about faith and justification. The Protestant church is furthered divided into denominations, including Presbyterian, Episcopal, Lutheran, Baptist, Methodist, and Wesleyan.

Sacraments: Visible signs of God's grace in the world. Catholic and Orthodox traditions have seven sacraments, while Protestants have two.
