Summa Theologica, Part III (Tertia Pars) From the Complete American Edition

"Summa Theologica, Part III (Tertia Pars)" by Saint Aquinas Thomas is a scholarly book from the 1200s that seriously looks into Christian beliefs, especially about Jesus Christ, the idea of God becoming human, and important religious ceremonies needed for being saved. This section of the bigger "Summa Theologica" gets into important questions about what it means that God came to Earth as Jesus and how that saves people. The beginning explains why it was necessary and right for God to become a man, Jesus. It stresses that Jesus was both God and human at the same time and asks questions about what Jesus knew, the kindness he showed, and why religious ceremonies exist, encouraging people to think about deep religious questions and how these ideas help them better get the picture of their trust and redemption in Christian faith.
