Original sentence: Cafeteria Christianity is a pejorative term used in general against individual Christians or Christian churches who are perceived as selectively following the precepts of their religion or what the Bible advances as the will or word of God.The implication is that the individual or group is actually advancing or acting upon their personal beliefs by deciding to reject some but follow other tenets of faith, rather than on a genuine interpretation or spiritual relationship with Christian doctrine.The label of "cafeteria christianity" has been used both by conservative or fundamentalist Christians for the purpose of encouraging more conformity with what they consider to be literal Christian doctrine, and also by less doctrinarian Christians or non-Christian skeptics to undermine the advocacy of certain Christian precepts by pointing out the claimed inconsistency of the advocate's position
Edited sentence: A good example would be observation of the Sabbath.But if a Cafeteria Christian doesn't like that one or finds it inconvenient, they are presumably free to ignore it.Cafeteria Christianity is a pejorative term used against Christians who feel they are free to pick and choose in general from the Law of God as recorded in the Torah or Pentateuch or specifically from the Ten Commandments.Closely related is Antinomianism where a believer believes they are above any moral guidelines or not subject to the Law of God as recorded.It is one of the Ten Commandments.Jesus' Sermon on the Mount, as recorded in Matthew 5-7, is fairly specific that not one yodh (the smallest letter of the Hebrew alphabet) or one iota (the smallest letter of the Greek alphabet, since the Torah was also available in Greek translation at the time as the Septuagint) was to be removed from the Law and Prophets until *all* (lion lies down with lamb, swords into plowshares, restoration of Jerusalem Temple and Davidic Messianic Kingdom ... according to the Prophets) has come to pass and that many would mislead in his name but you would know the true believers by their works.Of course, a Cafeteria Christian is free to ignore the Sermon on the Mount or claim it no longer applies in today's modern world or only applies to non-Christians or any other form of logic that one feels applies according to ones own personal tastes.This notion probably originates with Gnosticism where a believer has secret wisdom or personal insight into what commandments to select and what to ignore
