The concept of love (particularly how God loves) is a bit different on Calvinism. On Calvinism God loves the elect. Jesus died and rose again, for the few elect. This means that by definition, God as described by the consistent Calvinist is not omnibenevolent. Of course, a Calvinist could redefine the word “love” as it relates to God and claim that it is “loving” for God to allow those he loves to go to hell when they simply could not choose otherwise. In fact, this is the approach that many Calvinists take.
Even the idea of believing refers to individuals since only individuals can exercise faith; I do not see anything in the passage that would indicate that this “all” is restricted to something like all people groups, including some who can be saved. I do not think the passage even hints that this “all” is different from “all” including each person previously spoken of as under sin; of which “there is no distinction.” This understanding corresponds precisely with its usage before and in the following verses.
Two articles are added to the confession on singing hymns and the laying on of hands. More attention and information is given to the Lord’s Supper than Baptism. Baptism is affirmed for believers only through the church by immersion. The confession has similar understandings of salvation being a work of God in which He calls and provides grace to be saved. It is orthodox in its Christology and Eschatology. It differentiates between paedobaptism and New Testament baptism by believers.
Calvinism claims men are totally depraved in that they have no ability to respond to God unless and until God regenerates them or gives them spiritual life to THEN be able to repent and believe and be converted or saved. It is one thing to claim “no man come to God unless the Spirit draw him” and claim the necessity for regeneration for man’s response to God.
