I think it's a good thing that that opinion piece in the NC Register was written by a Jesuit. Good for the Jesuits for embracing diversity and allowing their members to seek out truth no matter what direction it takes them in.
The Jesuits are our real scholars. Teilhard de Chardin's works have changed my whole perspective about God and the universe (Louis Savary, a former Jesuit, has taken Teilhard's voluminous work and made it easily understandable for all of us. He is especially good at relating Teilhard to the Spiritual Exercises of St. Ignatius to bring Ignatius into the 21st century.)
My biggest gripe with the Eucharist-deniers is not what they say--it is their great big sin or omission, which not only politicizes their views but repels anyone who realizes that yes, there are commandments, precepts, spiritual and corporal works of mercy, etc. In doing so, their motives are suspect and they lose all credibility.
If they want respect, let them go after people on both sides of the aisle. If they want any suggestions on what possible sins Republican Catholics could have (excuse me while I get my smelling salts) they can consult their parishioners and will quickly get a voluminous list.
