Deus Caritas Est

The mens fellowship group that I am part of just wrapped up a Bible study on the Gospel of Mark. The next several months will be spent doing a discussion/study of the Papal Encyclical, Deus Caritas Est which was published on December 12, 2005 by Pope Benedict XVI. As an overview, the encyclical reflects on the different types of love and the different ways to love as revealed by God. It also expresses "The Practice of Love by the Church as a Community of Love".

As a group we have been unable to find a good study guide or commentary to use as an assistance to our group discussion. The one guide I was able to find came from a website that has significant bandwidth dedicated to Joyce Rupp and her writings. I choose to follow the guilt by association judgement model and have automatically disregarded it as a reliable resource for use in our study.

Do any of you know of a good study companion for a small group to use in reading this encyclical? We want something that is faithful to the Magisterium.
