✝️Intro to Christianity Unit 14 – Christianity and World Religions

Christianity, a monotheistic religion centered on Jesus Christ, has shaped world history for two millennia. It emphasizes belief in one God, salvation through faith, and the importance of love and compassion. The religion's core tenets include the Trinity, Jesus' divinity, and the concept of original sin. Christianity's rich history spans from its origins in 1st century Judea to its global presence today. The Bible serves as its sacred text, with various interpretations across denominations. Key practices include baptism, communion, and prayer, while major branches include Catholicism, Eastern Orthodoxy, and Protestantism.
