I am having a lot of discussion with my Christian friends on reformed theology. This is a huge subject!
How important is an adamant view on say predestination? The article of the month by A A Hodge
http://www.the-highway.com/articleAug02.html, in section VI suggests, according to my reading, that it is useful to have tension between two opposing views (Calvinism and Arminianism):
The difference between the best of either class is one of emphasis rather than of essential principle. Each is time complement of the other. Each is necessary to restrain, correct, and supply the one-sided strain of the other. They together give origin to the blended strain from which issues the perfect music which utters the perfect truth.
Note the quote itself should be read as I have cut out important parts where Hodge says that abstract historical arminianism is heresy.
What views do others have on this?
