Calvin's Binary view of humanity (Elect, Reprobate) is unscriptural: The Tripartite View

Calvin's binary view of humanity is unscriptural. Its clear a class of people exist who must choose, that haven't been predetermined one way or another. That elegant fact was known to the apostles:

The Foreordained (Elect) – Those predestined for salvation (Romans 8:29-30).

The Contingent (Middling) – Those whose final status depends on their response to God’s grace (Titus 2:11; Romans 2:6-7).

The Unyielding (Reprobate) – Those who persist in rejection and disobedience (2 Thessalonians 2:10-12; Romans 1:21-24).

The Tripartite View has strong support not only in Christian scripture but also in early Jewish teachings, specifically from the School of Hillel, which influenced the Apostle Paul (Acts 22:3; 23:6). This school taught a view of humanity divided into the Righteous, Middling, and Wicked, as documented in the Babylonian Talmud:

Rabbinic Teaching (Babylonian Talmud, Rosh Hashanah 16b-17a): 

 Three books are opened by God on the New Year</strong>: one for the thoroughly righteous, one for the thoroughly wicked, and one for the middling. 

The righteous are immediately inscribed for life. 

The wicked are immediately inscribed for death. 

The middling are left in suspense from New Year until the Day of Atonement, when their fate is determined based on their deeds.
