I am unclear about what is being suggested in the idea of a marriage by Priest's blessing?
Anyone who receives the Holy Mysteries has by virtue of that reception blessed their marriage. The way I understand a marriage to be Holy is by one or both parties receiving the Holy Mystery of Christ in Communion. It is only there that any marriage can be of one mind, one heart and one flesh.
When one's spouse does not follow the other into the Church, it is the sanctified spouse who brings the blessing into the marriage. It is they who bear the life giving body and blood of Christ into the marriage. It is they who have to consciously take up their Cross and follow Christ in loving their spouse, especially if that spouse is hostile to the faith. This also applies to those whose marriages are being broken on the stumbling stone of Christ and His Church.
Orthodox Marriage is a Mystery and/or Sacrament because two become one flesh in Christ. There is a great mystery here which seems to lie in that area of knowlege which St. Paul described as improper for men to utter, but it sanctifies and makes Holy the children of broken marriages.
1983? Was it in early November?
Ah hh, autumn the begining of time, the beginning of our salvation...a good time for marriage.
