The belief in one
GoD.
ChristianIty, JudaIsm
? and
IsLam are three famous examples of monotheistic religions. Note that the one
GoD may have several aspects, such as the concept of the
HolyTrinity in
ChristianIty. Monotheistic religions have a tendency to have strict sets of moral codes or laws (as they have a DivineLawgiver
? to provide them and justify them), often have a bias to one gender (due to the supposed gender of the
GoD in question), and appear to have become more prevalent later in civilisations, when order is a GoodThing
? and explanations for random natural disasters are beginning to come from other sources than angry
GoDs.
