Hi Philothei
, good question.
Among some Lutherans on both sides of this teaching there can be much passion. Lutherans hold Sola Scriptura but do not reject "tradition" the way that reformed protestants do.
When a tradition is at odds with Scripture or is prohibited by Scripture it must be rejected. When a tradition is not supported by Scripture, yet neither conflicts with, nor is prohibited by Scripture; it is considered Adiaphora (a thing of indifference). Adiaphora may be held, practised, and believed as "pious belief". Such things are not considered necessary for salvation; nor do we believe that the Church has the authority to mandate such teachings and beliefs as "articles of faith".
Yes, all of the early reformers held a belief in the EV of Mary; this is abundantly clear when one reads the Churches Confessions. Even in the final addition to the 1580 edition of the BoC (Formula of Concord, Solid Declaration Article VIII. The Person of Christ, 21), we read (bolding is mine):
Personally, I do accept this traditional belief regarding Mary. From studying Scripture, I believe that it alludes to this teaching. Likewise (and there are others more than willing to argue this as you well know) Scripture does not conflict with this belief either.
Traditionally, the early Church believed this. This belief may have originated with the Apostles, (but we don't know this for sure). We do know that at least some of those who were taught, either first hand or second hand by the Apostles held this belief.
In good faith, and in light of Scripture, I can not condemn those who do not accept and hold this belief.
Neither do I believe that those who do not hold this belief have any right or doctrinal mandate to condemn those of us who do.
Beliefs/unbelief in such as the EV and even the Dormation/Assumption will neither get one into heaven, nor damn them to hell.
Only Faith in Christ Jesus, the Son of the Living God, as given by the Holy Spirit will result in eternal salvation.
Such beliefs, held as pious opinion over the history of the Church give much more depth to our faith. Likewise, maintaining such traditions passed down from the early Church speaks of the timelessness of the the Church. Reformed protestants often view the Church in the here and now, disregarding history and tradition. Confessional Lutherans, and I believe the EO and RCC see the Church as eternal; the Bible speaks of a "cloud of witnesses"; who do they witness to if not us?
Blessings and Peace
