Claim: Christianity, in its early development, accommodated many traditional practices which at different times, accepted omens and practiced forms of ritual sacrifice; and concepts of "Divine Grace" or "Blessing", as they are described by believers, closely resemble what is referred to as "luck" (the phenomenon and belief that defines the experience of notably positive, negative, or improbable events) by others.
Evidence: Luck is the phenomenon and belief that defines the experience of notably positive, negative, or improbable events. In particular, Catholics and Reformed Protestants understand the attainment of grace in substantially different ways.
