When did Christians start using Christmas trees? I’m trying to read the whole Bible for the first time. What makes an animal clean or unclean? And how come no one ever tells us there were seven pairs of clean animals and one pair of unclean instead of just two-by-two? Will there be food in heaven? Sleep? Sex? Will Judgment Day happen before the New Heaven and Earth, or at the same time? Is Job a true story, or just fiction? Why does Jesus speak in parables? Why is the Catholic Church changing the words in the creed?
