Indeed, which so better, churches of people who are far more conservative and unified in basic values and beliefs, versus one who treats even proabortion, prosodomite, promuslim pols and supporters as members in life and in death, showing what she really believes in part, and whose overall fruit is those who support such.
And you have seen this one:

The author (James Swan) of the second image states,
“The problem is obvious - Rome, sedevacantists, traditionalist Catholics, Pope Michael-ists, Eastern Orthodox, Coptic Orthodox, and various other churches with incompatible teachings all appeal to this set and limited corpus of Scripture and Tradition. It would appear that the criticism against Sola Scriptura of multiple denominations applies to the Roman and EO rule of faith as well.
The Romanist or Orthodox might object: "But we're not in communion with those schismatics/heterodox/heretics!" Now, what if I were to reply, as a member of a Southern Baptist church, that, have no fear my non-Sola Scripturist friends, my church holds that everyone who's not a member of a Southern Baptist church is a schismatic/heterodox/heretic too? Would that make our Romanist or Orthodox friends feel better?
Or would that make them criticise us even more strongly: "See? You Sola Scripturists can't even hold communion with each other!"? Yep, my money's on that one, too. We're darned if we do and darned if we don't, but somehow if the Romanists or Orthodox don't hold communion with these other churches, that's just fine. Such special pleading is just...special...
If you want to compare unity and disunity, compare the adherences to the competing rules of faith. Or compare churches, like the Roman Church to the Southern Baptist Convention or the Pope Michael Catholic Church to the Orthodox Presbyterian Church. What do we find, if we do this?” (http://beggarsallreformation.blogspot.com/2009/12/special-pleading-of-sola-ecclesia-ists.html)

Over on my own blog, I have my own occasional feature called, Blueprint for Anarchy. What I've been doing is simply keeping track of all the times I come across Rome's zealous defenders disagreeing with each other, or pointing out the lack of clarity within Roman Catholicism as well as the confusion.
Robert Sungenis recently stated Rome's scholars are worse than Protestant liberals. Jimmy Akin recently chastised the interpretation of his priest saying, "This isn't exegetical rocket science." Steve Ray had some similar problems with a priest and concludes the church is "Always reforming, always in need of reform." Mark Shea accuses Robert Sungenis of lying. Sungenis says Scott Hahn misunderstands of the whole issue of justification. Over on the Catholic Answers forum, they recently had a heated discussion as to whether Scott Hahn teaches "prima scriptura." Tim Staples says he went to a mass in which the priest led the church in "the wave." Jimmy Akin says you can pray to whoever you want to, even if they aren't saints. Art Sippo says Mary should be Co-Redemptrix and Mediatrix of all Graces. Patrick Madrid disagreed with him. Karl Keating states, "Many Catholics are confused because some priests tell them contracepting is immoral, while others tell them the practice is morally neutral; some priests speak as though Mary had only one child, while others imply that she was the mother of the 'brethren of the Lord', some priests correctly explain the meaning of the Real Presence, while others refer to the Eucharist as only a symbol. Priests are authority figures, and lay people expect them to know and teach the faith accurately- not a safe assumption nowadays." Jim Burnham stated on Catholic Answers that Seventy percent of Roman Catholics do not understand the Eucharist.
I could go on and on. I didn't even mention any of my "We Have Apostolic Tradition"- The Unofficial Catholic Apologist Commentary " posts. In those posts, you can see that Catholic apologists disagree with each other when they interpret the Bible. Then there are the big issues, like evolution. If you want to see diversity of opinion, simply try and nail down a Catholic apologist or a Catholic theologian on it. You would think Catholic theologians could at least be unified on Luther and the Reformation. Some say Luther was sent by Satan, others think he wasn't such a bad guy.
Shall we conclude that an infallible interpreter + infallible tradition + infallible scripture = harmony? The facts speak for themselves
