Welcome to the forum from yet another Lutheran. I trust that you will find here, as I have, a lot of good discussion about matters of faith.
Deaconesses are part of the Lutheran tradition, introduced into this country in part by the immigration of some of the German schwestern, who were nurses. A group of these schwestern were instrumental in establishing Lankenau Hospital in the suburbs of Philadelphia. Deaconesses also served, and continue to serve, in congregations in a variety of roles.
The Lutheran tradition refers to its clergy as pastors (shepherds). While a priest is seen, at least in part, as a mediator between God and man, the pastor is charged with the responsibilities laid on Peter by our Lord – “feed my lambs…tend my sheep…feed my sheep.” The pastor tends and feeds the flock with Word and Sacrament and with pastoral ministry. Jesus himself, our great high priest, remains the mediator between God and man.
With regard to the Rosary, it has not been a part of Lutheran tradition for a variety of reasons. From a Lutheran perspective, much in it is wonderful to meditate on – the Apostles Creed, the Lord’s Prayer, the Gloria Patri, most of the mysteries (save the Assumption and the Coronation of Mary), and the first part of the Hail Mary which comes from the scriptural accounts of the Annunciation and the Visitation. The Salve Regina is a problem as it seems to exhibit a level of devotion to Mary that is excessive to our Lutheran sensibilities. I hasten to add that I consider Mary to the very model of faith and obedience. But, for many Lutherans the Rosary is “too Catholic.”
Just a few thoughts.
