Only in your mind. Calvinism and Armenianism are directly opposed in their 5 points. Here is a text comparison between them. Each point has a description with one and then the other one right below it. Personally I am a Calvinist but have researched Armenianism and found many verses backing it up. I therefore respectfully agree to disagree with Armenianism.

The five points of Arminianism (from Jacobus Arminius 1559-1609) are in contrast to the five points of Calvinism (from from John (Jehan) Calvin 1509-1564). The Arminian five points with the Calvinist points listed beneath it are listed below. First Armenian then Calvinism below it. There are web sites having a lengthy discussion about each point and several Bible verses backing it up. The Apostles Creed defines what a Christian must believe. Anything outside it is agree to disagree. This is an example of the agree to disagree.
