[Schoonenberg’s comments can be portrayed through a familiar intersection, the message underlying the word ‘religion’.
Sin and virtue are actualities that both situate and emerge from our dispositions and conscience (free will). The physical ability to love goes with the dispositions. The moral ability (or inability) to love goes with conscience.
I label ‘the moral ability to love’ ‘consciencefree’.
Here, ‘free’ means freedom from a thinkgroup that makes you a slave to a sinful behavior.
The ‘moral inability to love’, corresponds to ‘consciencelacking’, which means a conscience lacking in freedom.]
