Understanding The Ontological Argument Through Love: The Paradox Between Faith And Reason, Bill Goodson

Masters Theses

This thesis argues that while the ontological argument as presented by Saint Anselm of Canterbury offers a formal logical explanation for the existence of God, love is presented as the bridge that enables the skeptic and the believer to engage the argument from a relational and experiential perspective in joining faith and reason through God’s divine love. The paradox found therein is that love, being kind, generous, and caring, initially appears to be too soft for the hard truth and sheer facts of reason. The calling of the theologian is to expose the good news of his faith, and his …
