I disagree with you Drearyweather,
Though context may have a bearing on some statements, things referred to in Mathew 7:21-23 are absolute which can mean one and the same thing in any context. Interestingly, phrases such as “the poor in spirit, those who mourn, the meek, those who hunger and thirst for righteousness, the merciful, the pure in heart, the peacemakers, those who are persecuted because of righteousness” etc are prima facie refer to those what they mean—not to a particular faith or organization.
In addition, Jesus made it sure that no one would interpret it in any other ways by elaborating it in the simplest illustration of sheep and goat (Mathew 25:31-46) where it is described with absolute clarity that judgment is based on whether humans acted humanely or not, not based on one’s belief.
