This is very clear-headed thinking in America Magazine
These questions are not negligible. Cardinal James Gibbons, when he received the "Red Hat," in a memorable sermon at the church of Santa Maria in Trastevere, strongly praised the tremendous benefit that came to the church in our country because of the separation of church and state. During our more than two hundred years of history, the American bishops have until very recently steadfastly held to the position of making judgments about policy but never judgments about persons in the political arena. One reason for this position was that the episcopate recognized that the greater good of the mission of the church would be served in this way.
Taking account of what serves the greater good of the mission of the church is not opportunism. It is what Catholic tradition calls prudence. The saints have used various words for this cardinal virtue: discretion, discernment, practical wisdom. The great teacher of discernment, St. Ignatius Loyola, points out in this context the serious evil of the temptation of the good. Not everything that seems good is in fact good. Weighing, discernment and discretion are necessary even in things that seem on the face of it to be good. There is always the twin issue of the objective itself and the means of achieving it. One may be good, the other not.
The bigger question though which Bishop Quinn addressed in the first few paragraphs of the article is a doozy: How do unborn get served in the end by either withdrawing the invitation or by allowing President Obama to speak? Which ends up serving their needs best? I agree with Bishop Quinn on this point:
But it does not improve the likelihood of making progress on this and other issues of common concern if we adopt the clenched fist approach. The president has given ample evidence that he is a man of good will, of keen intelligence, desirous of listening and capable of weighing seriously other views. The Directory for the Pastoral Ministry of Bishops, citing Augustine, points out that “ Certain situations cannot be resolved with asperity or hardness” and goes on to say “(B)ecause his daily pastoral concerns give the Bishop greater scope for personal decision-making, his scope for error is also greater, however good his intentions: this thought should encourage him to remain open to dialog with others, always ready to learn, to seek and accept the advice of others.”
There's a lot of good thoughts in the early part of the article as well which you should read by going here
