I have found generally apologetics to consist of answering the “what” questions, which is usually after making an initial shift in the claim. eg. You Catholics worship Mary. The apologetics then becomes “what” in fact Catholics believe. It shifts the “what” worship to the “what” venerate. It becomes the “what” no it doesn’t take our focus off Jesus Christ, it becomes the “what” it focuses us on Jesus Christ.
With that background I would like to hear some thoughts on the more important “why” and “how” questions of the “Communion of Saints”. Why it is important to us, why it is important to them, why it is important to God? Why do we care? Why would they care? Why does God care? How it affects our lifes our faith? How this communion benefits?
