It is often claimed that one insuperable difference between Protestants and Catholics is that Protestants, since Luther, believe in the priesthood of all believers, while Catholics believe Christians need a priest to bring them to God. Today this is usually a Protestant accusation against Catholics, although in the sixteenth century Luther’s notion of the priesthood of all believers, including illiterate and semi-literate peasants, did come in for a certain amount of ridicule from some of the more educated members of the clergy. Some of the wilder branches of Protestantism have gone further than Luther, even rejecting, on the claimed basis of the “priesthood of all believers,” any ordained clergy whatsoever (this includes the Plymouth Brethren and the Quakers), while many “Bible-believing” Protestants draw a sharp distinction between Roman Catholic priests and their own pastors or elders. As with so many things, however, the disagreement between the denominations over the scope of the priesthood is based more on an argument over words than over the substance of what the Bible says. There are substantive disagreements in Roman Catholic and various Protestant understandings of priesthood(s), but the “argument” over the priesthood or not of all believers can safely be put down to a deficiency of northern European languages like English, which have one word where Greek has two, and a desire on both sides of the argument to affirm the superiority of their group over those who disagree with them.
Will the real Church please stand up? Go to a phone directory of any moderately sized settlement and see if the listings for “churches” don’t rapidly get bewildering. Indeed, such an exercise is often an education into varieties of Christianity we didn’t know existed! How should those who worship Christ sort through this denominational chaos?
One method frequently suggested by Roman Catholics, Eastern Orthodox, and Disciples of Christ (along with a few Baptists, on occasion) is to look at the evidence for early Christianity and see which contemporary denomination is most similar to the churches of the apostles and their successors. This is the argument from similarity. I recently read a blog post making this argument against Protestants of all stripes, and a commentator here pressed me to consider the same line of reasoning. It was not the first time. I have heard this argument made in favor of multiple different branches of contemporary Christianity. I like to imagine the question by asking which church would look most familiar to the apostle Peter or any of the other earliest Christians, if he were sent on a time-travel expedition from AD 60 to the present. I prefer someone else to Jesus for this exercise because Jesus is the God who knows the hearts, and this is usually posed as a question about external appearances. (more…)
