Our current Alienist problem in the Western Calvinist Churches is a reflection of the decline of genuine Reformed soteriology. Biblical and Historical Calvinism has always advocated for limited damnation (particular redemption), where Christ is put forth as a sacrifice for only His people.
In the Reformed (Biblical) understanding God’s chief passion is Himself. In the Reformed (Biblical) understanding God does all He does for His own interest. He pursues His own interests and in the context of particular redemption this means He willfully limits His affections to His people.
Reformed folk understood that this had implications. As God’s love was particular so Reformed folk refused the idea of “the Brotherhood of all men.” If God restricts His love so that it is particular so man’s love can be particular as well. In other words, God’s love for His own is a communicable attribute.
If God does not restrict His love so that He loves all men indiscriminately then men must be pluralists and love all men indiscriminately. This is the destruction of family, clan, and nations and the embrace of universal love.
The connection here is that as Calvinists become weak on Limited Damnation they become strong on the Liberal Doctrines of the “Fatherhood of God over all men,” and “the Brotherhood of all men.”
