Ignatius, I believe, would not be happy to think that we were celebrating him. After his conversion, Ignatius wanted to point everyone to Jesus. It is, for instance, why I am a Jesuit and not an Ignatian.
So, today, we give thanks to God for what God gave to the world through this energetic and eccentric Basque soldier from 500 years ago.
May we who count ourselves as blessed by Ignatian Spirituality be as open to God working in our lives as Ignatius was in his.
Ad Majorem Dei Gloriam.
