 Because it made these changes using claims of tradition and not from scripture, the Church -- in the opinion of those adhering to this concept -- has fallen into apostasy.A major thread of this perception is the suggestion that, to attract and convert people to Christianity, the church in Rome incorporated pagan beliefs and practices within the Christian religion, mostly Graeco-Roman rituals, mysteries, and festivals.For example, Easter has been described as a pagan substitute for the Jewish Passover, although neither Jesus nor his Apostles enjoined the keeping of this or any other festival.
