Do Lutherans now consider the followers of Zwingli and Calvin to be their brothers in Christ and members of the Body of Christ? From here I found out that Luther did not believe that Zwingli was saved. What about the followers of Luther in these days? Do they consider Calvinists and Zwinglinists as their brothers in Christ?

Three of the most influential reformers, Martin Luther, John Calvin, and Huldrych Zwingli, took very different approaches to music in corporate worship. Of the three, Zwingli was the most accomplished musician, but he was also the most negative about music in worship – he apparently rejected it completely. Not even Calvin's unaccompanied psalm-singing was sufficient for him. Jeremy S. Begbie writes: > Zwingli was ruthlessly consistent—the intricacies of Latin polyphony, the sounds of the organ, the chanting of the Psalms, the setting of the Mass, even the unaccompanied unison singing of the Psalms in the vernacular (as Calvin allowed) must all go. ([*Resounding Truth*, 115](https://books.google.com/books?id=bLqOBmjGznAC&pg=PA115)) Zwingli's recommendations were apparently put into effect in Zurich: organs were silenced and then destroyed, and in 1525 "the city council enacted the ban on singing in worship." I'd like to explore the reasons for this view. Begbie provides some insight – the [regulative principle of worship](https://en.wikipedia.org/wiki/Regulative_principle_of_worship) played a role, for example, whereas a fear of the worldliness of music did not. But I'd like to see more detail, particularly from the writings of Zwingli himself. For example: - How did Zwingli deal with the apparent commands to sing in [Colossians 3:16](https://www.biblegateway.com/passage/?search=colossians+3%3A16&version=ESV) and [Ephesians 5:19](https://www.biblegateway.com/passage/?search=ephesians+5%3A19&version=ESV) ? - Why isn't the use of instruments in the Old Testament precedent for their use today? - Did he see a difference between a corporately recited prayer and a corporately sung psalm or hymn? - Why not at least unaccompanied exclusive psalmody, like Calvin?

Did Martin Luther and Zwingli not consider each other brothers in Christ and members of the Body of Christ? Did they ever state that in a written form?

Do Mormons believe in transubstantiation, or consubstantiation, or the Lutheran "sacramental union", or the Calvinist "mystical presence", or perhaps a more Zwinglian "purely symbolic" approach? Is there a quick and easy way to sum up the Mormon view on the Eucharist such as I have enumerated above? (Leaving aside the fact that they use water rather than wine or grape juice)

During the Reformation, Protestant reformers such as Huldrych Zwingli and John Calvin promoted Iconoclasm among their followers. I have found information about Luther opposing it, but little about why. Why exactly did Luther oppose iconoclasm when other leaders supported it?  *Illustration in a deluxe Luther Bible showing God creating the world*  *The same illustration in a deluxe Luther Bible owned by Count Joachim , in which he erased the depiction of God because of his support of iconoclasm*

[Berengar of Tours](https://en.wikipedia.org/wiki/Berengar_of_Tours) played a major role in the Second Eucharistic Controversy, which took place in the 11th century. He opposed the increasing acceptance of proto-transubstantiation doctrines, arguing against materialist understandings of the elements on biblical and philosophical grounds. Everett Ferguson ([*Church History*, I, 21.II](https://books.google.com/books?id=mRQwAAAAQBAJ&pg=PT373)) summarizes Berengar's view as "dynamic symbolism": > The consecrated elements do not become the body and blood, but produce the effects of Christ on the recipient. Today the word "symbolic" in reference to the Lord's Supper is often connected to the reformer [Huldrych Zwingli](https://en.wikipedia.org/wiki/Huldrych_Zwingli) , who sees communion as simply a symbolic memorial of the Last Supper. But I wonder how close the views were of these two thinkers – how similar were the views of Berengar and Zwingli on the nature, purpose, and effects of the elements in the Eucharist?

I know that Switzerland and southern Germany was the birthplace of anabaptism, did it come from Ulrich Zwingli? Or was there another more influential person out of the reformation that encouraged anabaptism? Modern anabaptist churches (to my knowledge) are all descendents of German Brethren churches. Where would that put Switzerland?

Which languages did Huldrych Zwingli know? As far as I know, he knew Latin and, of course, he knew his own mother tongue (which was German or Romanch?), but did he know some other languages? I am especially interested in whether he knew Hebrew or Greek.
