This surprising quote from someone I have often disagreed with theologically, has encouraged me to continue to find grace even from those in other Christian traditions.
"After the reading of Scripture, which I strenuously inculcate, and more than any other ... I recommend that the Commentaries of Calvin be read ... For I affirm that in the interpretation of the Scriptures Calvin is incomparable, and that his Commentaries are more to be valued than anything that is handed down to us in the writings of the Fathers -- so much that I concede to him a certain spirit of prophecy in which he stands distinguished above others, above most, indeed, above all" -Jacobus Arminius (1560-1609) - Jacobus Arminius, Monergism website
With all the conversations that I have had or heard on Arminianism vs. Calvinism or Reformation theology, I found this quote amazing to say the least. While I don't think that simply displaying this quote will solve the impasse, I think it does show an example of how there was a remarkable willingness to give credit where it was due.
For more interesting and helpful theology sources (more than you will ever be able to read!) I recommend www.monergism.com. It is decidedly in the Reformation tradition but I think it will challenge all who come with a faith seeking understanding that desires to be Biblical. Some of the articles are quite polemical but this can also serve as a corrective to growing apathetic with issues of truth.
