What is Christianity?Christianity is a global religion centered on the life and teachings of Jesus Christ, who followers believe is the Son of God. It's a monotheistic faith, meaning Christians believe in one God who exists in three co-equal persons: God the Father, God the Son (Jesus Christ), and the Holy Spirit. Christianity is based on the Bible, with the Old Testament and New Testament serving as sacred texts.
What is Science?Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to the works of Ancient Egyptians and Mesopotamians, whose contributions entered and shaped Greek natural philosophy of classical antiquity. After the fall of the Western Roman Empire, knowledge of Greek science deteriorated in Western Europe during the Middle Ages but flourished in the Islamic Golden Age. Modern science is typically divided into three major branches that consist of the natural sciences (e.g. biology, chemistry, physics), which study nature in the broadest sense; the social sciences (e.g. psychology, sociology, economics), which study individuals and societies; and the formal sciences (e.g. mathematics, logic, theoretical computer science), which study abstract concepts.
What is Sin?In Abrahamic contexts, sin is the act of violating God's will. Sin can also be viewed as anything that violates the ideal relationship between an individual and God; or as any diversion from the ideal order for human living. To sin has been defined as "to miss the mark".
Sins fall in a spectrum from minor errors to deadly misdeeds. Catholicism regards the least corrupt sins as venial sins which are part of human living and carry immediate consequences on earth, and, if unrepented for, more painful purgation, assuming the person is destined to heaven, as it is written in the formation letter "Purgatory", "most of the early Fathers of the Church speak of a cleansing fire, though we cannot tell whether this means actual or spiritual fire."
Conversely, sins of great evil are mortal sins which bring the consequence of hell if they are not addressed either through an act of perfect contrition or going to confession about them.
