Felix Manz, another radical leader, was born in Zürich, where his father was a canon of Grossmünster church.
Though records of his education are scant, there is evidence that he had a liberal education, with a thorough knowledge of Hebrew, Greek and Latin.
Manz had become a follower of Zwingli after he came to Zürich in 1519.
When Grebel joined the group in 1521, he and Manz had become friends.
They questioned the mass, the nature of church and state connections, and infant baptism.
After the Second Disputation of Zürich in 1523, they had become dissatisfied, believing that Zwingli's plans for reform had been compromised with the city council.
Grebel, Manz and others have made several attempts to plead their position.
Several parents refuse to have their children baptized.
A public debate is held on January 17, 1525, and the council decides in favor of Zwingli.
Anyone refusing to have their children baptized is required to leave Zurich.
The radicals ignore these measures and on January 21, they meet at the house of the mother of Manz.
Grebel and a third leader, George Blaurock, perform the first recorded Anabaptist adult baptisms: Grebel baptizes Blaurock, and Blaurock in turn baptizes the others.
This makes complete the break with Zwingli and the council, and forms the first church of the Radical Reformation.
On February 2, the council repeats the requirement on the baptism of all babies and some who fail to comply are arrested and fined, Manz and Blaurock among them.
Zwingli and Jud interview them and more debates are held before the Zurich council.
Meanwhile, the new teachings continue to spread to other parts of the Confederation as well as a number of Swabian towns.
Although the council had hesitated in abolishing the mass, the decrease in the exercise of traditional piety has allowed pastors to be unofficially released from the requirement of celebrating mass.
As individual pastors alter their practices as each sees fit, Zwingli is prompted to address this disorganized situation by designing a communion liturgy in the German language.
This is published in Aktion oder Brauch des Nachtmahls (Act or Custom of the Supper).
Shortly before Easter, Zwingli and his closest associates request the council to cancel the mass and to introduce the new public order of worship.
On Maundy Thursday, April 13, 1525, Zwingli celebrates communion under his new liturgy.
Wooden cups and plates are used to avoid any outward displays of formality.
The congregation sits at set tables to emphasize the meal aspect of the sacrament.
The sermon is the focal point of the service and there is no organ music or singing.
The importance of the sermon in the worship service is underlined by Zwingli's proposal to limit the celebration of communion to four times a year.
For some time, Zwingli has accused mendicant orders of hypocrisy and demanded their abolition in order to support the truly poor.
He suggests the monasteries be changed into hospitals and welfare institutions and incorporate their wealth into a welfare fund.
This is done by reorganizing the foundations of the Grossmünster and Fraumünster and pensioning off remaining nuns and monks.
The council secularizes the church properties and establishes new welfare programs for the poor.
Zwingli requess permission to establish a Latin school, the Prophezei (Prophecy) or Carolinum, at the Grossmünster.
The council agrees and it is officially opened on June 19, 1525 with Zwingli and Jud as teachers.
It serves to retrain and reeducate the clergy.
The Zurich Bible translation, traditionally attributed to Zwingli and printed by Christoph Froschauer, bears the mark of teamwork from the Prophecy school.
Scholars have not yet attempted to clarify Zwingli's share of the work based on external and stylistic evidence.
On November 6–8, the last debate on the subject of baptism took place in the Grossmünster.
Grebel, Manz, and Blaurock defend their cause before Zwingli, Jud, and other reformers.
There is no serious exchange of views as each side will not move from their positions and the debates degenerate into an uproar, each side shouting abuse at the other.
