Are all religious rituals sacred?
No. Those that are in the service of worshiping idols are not sacred. Those that are not in reverence of Christ Jesus are not sacred. Even rituals in Christian circles that are more about the performance of the ceremony than what aspect of holy God it should signify are also not sacred. For example, some Christian circles practice using “prayer cloths” or “holy water” as a means of bestowing miraculous power on the recipients. The focus becomes the cloth or the water and not the GOD who is the actual miracle worker.
