2 AnswersRadio1 decade agoWhat rituals did Jesus teach, if any?
Only ritual I remember reading in the New Testament is the "Our Father" prayer, but besides that...Reason I ask this is because the Catholic church seems to be a sect of what Jesus really taught us. For example, Jesus never said anything about wearing a cross, he never said anything about attending mass as we now know it (who scripted the mass anyways?), Jesus never said anything about no Christmas Tree, Adventus, The Via Crusis etc. In fact he was a very simple man, with a very strong message which actually condemmed the people who were praying in public etc.
What are your thoughts on Jesus and the Contemporary Catholic Church?
