I learnt a new theological term today. But I apologise to my Reformed friends if it is an objectionable phrase - one website referred to it as 'perjorative'.
My Wesley Studies notes refer to Wesley's dislike of Calvin's concept of double predestination - of which I had never heard before - and which, I suspect, was not Calvin's idea anyway.
So what is it? The dual sense of predestination as regards both election and reprobation. Here again I was stuck - I've not (as far as I can remember) come across the term reprobation before. Election is the idea that God chooses beforehand who will be saved (as far as we can see arbitrarily) and he causes these people, by his grace, to turn to him in repentance.
Reprobation is the symmetrical idea that God chooses beforehand who will not be saved and causes them to sin and thus earn their condemnation. This carries the confusion of the sense that God causes these people to sin and thus he is surely as much at fault as the sinner. As far as I understand, most Reformed thinkers don't find the doctrine of reprobation necessary. Because, surely, human beings have sinned and are already condemned, there is no need to supply a symmetrical doctrine to election.
Which is probably why I haven't come across the term double predestination.
As Methodists and from the Wesleyan tradition, we believe that God provides, in his grace, the opportunity for all to repent and turn to him, and that the final choice is ours. We believe that he predestined that all who believe in Jesus will be saved - so that he chose the way, not the people. I'm ok with that - very ok, in fact.
[As a matter of interest, I had to find out about double predestination via Google, but I do hope that our theological discussions will sometime get to that level. To be fair, we were short of time.]
