Not all forms, just all nicean forms, which comprises all the denominations most people care about, but what some folks consider offshoot christian religions like Jehovah's Witnesses and Mormons don't ascribe to it for various reasons.
That's a definition understood by nicean christians as the nicean creed was basically developed in a trial to say who is and isn't christian and exile the not christians who wouldn't cooperate
Academically I don't think there is universal agreement on if that standard should be taken at face value.
