what does the bible say?
Folk religion refers to religious beliefs and practices that arise from human tradition, cultural custom, or local superstitions. There are many forms of folk religion, with about 10% of the world's population practicing some form of it. Because of its wide variety, no two folk religions are identical. However, what unites them is their drawing on specific ethnic or regional traditions to form a culturally specific set of beliefs and practices. We are to reject all religion that originates outside of God’s Word because God is God and He does not permit people to decide for themselves how He should be worshiped. He warned against adopting religious practices simply because they are spiritually familiar (Leviticus 18:3; Deuteronomy 12:30–32; Isaiah 29:13) and condemned attempts to gain blessing or favor through rituals apart from faith and obedience (Hosea 6:6; John 14:15; Ephesians 2:8-9). For this reason, believers are to evaluate religious practices by whether or not they are grounded in the Bible, not by their cultural importance. Practices rooted in human tradition rather than God’s Word must be rejected (Mark 7:7–9; Colossians 2:8).
