I’m going to open this post with chapter 40 from Clement’s letter to the Corinthians.
Since, therefore, these things have been made manifest before unto us, and since we have looked into the depths of the divine knowledge, we ought to do everything in order, whatsoever the Lord hath commanded us to do at the appointed seasons, and to perform the offerings and liturgies. These he hath not commanded to be done at random or in disorder, but at fixed times and seasons. But when and by whom he wisheth them to be fulfilled he himself hath decided by his supreme will; that all things, being done piously, according to his good pleasure, might be acceptable to his will. They, therefore, who at the appointed seasons make their offerings are acceptable and blessed; for while following the laws of the Master they do not completely sin. For to the High Priest were assigned special services, and to the priests a special place hath been appointed; and on the Levites special duties are imposed. But he that is a layman is bound by the ordinances of laymen.
In this context, we see reinforced what Paul had written in his first letter to Corinth and the teaching from the Didache (redundant since Didache means Teaching, but I couldn’t think of a better way to phrase it). The offerings (in this context eucharist) and the liturgies (the work of worship of the people) are to be done in order and at fixed times and seasons, not at random or in disorder. Further, this order had been commanded by the Lord. In addition to their schisms and divisiveness, one of Paul’s chief concerns with the Corinthian church a generation or so earlier had been their disorder in worship. It seems that many of the bad tendencies of this church had persisted.
I’m not a Greek scholar though I’ve picked up a passing familiarity with some of the rudiments of the language over the years. From past experience, the English word “laymen” above probably translated laos or laoikos. I find that the modern understanding of laymen or laity doesn’t precisely jibe with the ancient understanding. It took me a while to begin to see it, myself. In the ancient understanding, the laiokos were not the unordained. Drawing heavily on Hebrews, they understood that the people of God were reconstituted in Christ as a royal priesthood with one high priest, Jesus the Christ. That was a shift because before Christ only the sons of Aaron out of the people of God formed the priestly class. The laoikos then were those ordained into the first order of the priesthood in Baptism. As such, the people were all responsible for their part in the liturgy, in the offerings (a priest could not perform the liturgy of the Eucharist or communion alone or without the people), and in their priestly ministrations in the world.
The best illustration of the distinctions of orders actually comes a few centuries later. St. Ambrose of Milan, though his sister and mother were Christian, had not yet been baptized when the Arian bishop of Milan died. (It is important to note that it was not uncommon to delay baptism at that time because of the question of whether or not intentional sins committed after baptism could be forgiven.) Ambrose was a gifted orator and lawyer and was attempting to maintain order in a uprising of the orthodox (non-Arian) Christians of Milan. As he was doing so, the people acclaimed his as their bishop. He was immediately baptized and then ordained to the diaconate and then priesthood on successive days before being elevated to the episcopate the next week.
So there is one priesthood consisting of all the people of God and four orders within that priesthood with one eternal High Priest in Jesus Christ. We are all priests and priestesses of at least the first order if we are baptized in Christ. When we lose sight of that reality, things get muddled pretty quickly.
I’m going to close my reflection on this letter with the following section from chapter 46.
Why are there strivings, and anger, and division, and war among you? Have we not one God and one Christ? Is not the Spirit of grace, which was poured out upon us, one? Is not our calling one in Christ? Why do we tear apart and rend asunder the members of Christ, and make sedition against our body, and come to such a degree of madness that we forget we are members one of another? Remember the words of our Lord Jesus, for he said, Woe unto that man; it were good for him if he had never been born, rather than that he should cause one of my elect to offend. It were better for him that a millstone were tied about him, and that he were cast into the sea, rather than that he should cause one of my little ones to offend. This your schism has perverted many; hath cast many into despondency; many into doubt; all of us into grief, and, as yet, your sedition remaineth.
It’s important to absorb the tenor of this statement and others like it. This call to oneness tends to permeate discussions of the Eucharist in the ancient writings. Clement, of course, is echoing Paul. He’s not really saying anything new. This is an application of the tradition of the apostles which we believe according to the Holy Scriptures of the New Testament they received directly from Christ.
