Despite the radicalism of early Protestantism with regard to many ancient Catholic "distinctives," such as the Communion of the Saints, Penance, Purgatory, Infused Justification, the Papacy, the priesthood, sacramental marriage, etc., it may surprise many to discover that Martin Luther was rather conservative in some of his doctrinal views, such as on baptismal regeneration, the Eucharist, and particularly the Blessed Virgin Mary.
Praying to Mary is not a Lutheran tradition.
I hear that some pray the rosary.
Doctrine has also converged a little bit, most notably with the Joint Declaration on Justification signed a few years ago.
