While reformers such as Martin Luther, Huldrych Zwingli and John Calvin at different points in their writings had expressed what seem to be examples of a residual catholic Marian piety, the Protestant emphasis on sola scriptura, solus Christus, soli Deo gloria, among others kept the honoring of Mary to a minimum, and Protestant teaching about Mary co-terminous with her short part in scripture and creeds. A newer Protestant view of Mary emerging out of the Evangelical movement sees Mary as a feisty, assertive, and radically Christian woman.
Some early Protestants venerated and honored Mary. Martin Luther said of Mary:
the honor given to the mother of God has been rooted so deeply into the hearts of men that no one wants to hear any opposition to this celebration... We also grant that she should be honored, since we, according to Saint Paul's words are indebted to show honor one to another for the sake of the One who dwells in us, Jesus Christ. Therefore we have an obligation to honor Mary. But be careful to give her honor that is fitting. Unfortunately, I worry that we give her all too high an honor for she is accorded much more esteem than she should be given or than she accounted to herself.
John Calvin said, "It cannot be denied that God in choosing and destining Mary to be the Mother of his Son, granted her the highest honor." Zwingli said, "I esteem immensely the Mother of God" and "The more the honor and love of Christ increases among men, so much the esteem and honor given to Mary should grow".
Thus the idea of respect and high honour was not rejected by the first Protestants; but rather it was the matter of degrees of honor given to Mary, as the mother of Jesus, that Protestant Reformers were concerned with, and therefore the practical implications for Mariology are still a matter of debate.
