In theory, Arminians affirm unlimited atonement while they disaffirm reprobation. They also claim that God is no respecter of persons. Rather, God loves the “world,” which they define as every human being.
But as it turns out, Arminian nomenclature has an esoteric sense. In practice, Arminians are really Manicheans. They divvy up the “world “into a binary caste-system consisting of elect Arminians and reprobate devil-worshipers.
(N.B. A devil-worshipper is a synonym for Calvinist.)
Devil-worshipers (aka Calvinists) are devilish because they worship a devilish God, and you are what you worship.
Complementing their Manichaean eschatology is a Manichaean code of conduct. There’s one code of conduct for elect Arminians, and another code of conduct for reprobate devil-worshipers (otherwise known as Calvinists).
Elect Arminians love all and only their own kind–which is to say, fellow Arminians. God died for elect Arminians, not for Reformed Satanists.
You don’t have to be loving in the way treat demon seed since they’re just a bunch of hell-bound reprobates. The Sermon on the Mount only kicks in case you’re dealing with the children of light (i.e. Arminians), and not if you’re dealing with the children of darkness (i.e. Calvinists).
However, under no circumstances should this be construed as hypocritical. We naturally have different standards for the children of God and the spawn of Satan. Different paternity, different caste, different standards.
