Oriental Orthodox, Eastern Orthodox, Roman Catholic Eastern/Western agree on 7 Sacraments and in particular the Eucharist. Those that disagree have not reformed but have substituted unity under other than that which unites the aforementioned.
Testimony from the Early Church and Ancient Church suggests your mind is infected by Western Philosophical constructs that blind you. There is no Ancient, Medieval or Modern Church except in your own mind. Satisfy yourself that Christ is the same yesterday, today and tomorrow. Satisfy yourself that Jesus is the way the truth and the light. If the Church is the body of Christ, the Bride of Christ and Christ is the head do you want me to accept the Bride as Ancient, Medieval and Modern…for how can Christ change…does the truth change, can the body reform the entire corpus and head, the body adapts to the world or the world adapts to the body. The OHCAC got it right in Gaudium et spes…”The Church in the Modern World”…The OHCAC understands this semantic difference that you do not.
We believe the faith was already delivered once and in its fullness. Christ never Changes. I don’t see the 7 sacraments as a Point of tension. The Orthodox have never actually counted their sacraments but they generally hold to 7. As do Anglicans although the Eucharist and Baptism are the most important that we consider generally necessary to salvation. I came across an article from a Lutheran Priest that stuck out to me.
#20 – What Is a Sacrament?
What is a sacrament? If we try to answer that question from the Scriptures, we have a problem. For the word “sacrament” is simply not found in the Bible.
The word “sacrament” was used by the ancient church to describe the most im-portant “holy acts” in the life of a Christian. It was used to describe some special action performed in order to nourish the Christian life for its growth to the glory of God.
How Many Sacraments?
Just as Christian denominations today disagree on the number of sacraments, so it was among Christians in the church over a thousand years ago.
Some listed only a few sacraments. Others listed over thirty. Finally, the great twelfth century theology Peter Lombard tried to convince everybody that there were sev-en sacraments – no more and no less. Many Christians still agree with him.
Lutherans have always taught that the numbering of the sacraments is unimpor-tant. The Apology of the Augsburg Confession states: “We do not think it makes much difference if, for purposes of teaching, the enumeration varies, provided what is handed down in Scripture is preserved” (XIII, 2).
What then is important? It is important to preserve these rites and ceremonies which Scripture tells us Christ instituted, and which proclaim and seal God’s mercy and grace in the lives of men.
There are many religious ceremonies and practices described in the Bible (prayer, the washing of feet, fasting, etc.), but not all of them proclaim and seal God’s mercy and forgiveness.
The Church’s “Holy Acts”
The church has the right to create ceremonies, rites, and customs, to teach, guide, and train its members. But is it really wise to call such rites and ceremonies “sacra-ments” right along with those acts instituted by Christ? Doesn’t such a general use of the word tend to place all “holy acts” on the same level?
The Lutheran Church teaches that we should carefully distinguish between those acts instituted by Christ to actually communicate and seal God’s promises, and those acts created by the church to teach and remind people of God’s will. Luther said that God’s promises create the church, but the church doesn’t create God’s promises.
God’s “Holy Acts”
The Church of the Augsburg Confession recognizes three rites which deserve the name “sacrament” because Christ himself gave them to the church to save men. These three are: Baptism, the Lord’s Supper, and Absolution (Apology, XIII, 4).
Two other rites, ordination and matrimony, could be called sacraments with cer-tain qualifications (Apology, XIII, 12, 14). Our Lord Jesus Christ instituted the pastoral ministry, and God the Father established marriage; and both estates are involved with the forgiveness of sins and the general communicating of God’s saving grace. Yet, the cere-monies of ordination and matrimony were not instituted directly by Christ, and neither of them directly brings God’s forgiveness.
Once again, it is not a sin to call those other things “sacraments,” but Lutherans stress that it is unwise because it might weaken our special appreciation of those most precious gifts given directly by Christ to the church in order for the church to live.
