Heinrich Bullinger and John Calvin agreed on a common doctrine of the Eucharist in 1549. They signed a mutual agreement in Zurich, includes 26 items:≪Consensus Tigurinus≫, which was published in Zurich and Geneva in 1551. The agreement between the Zurich and the Geneva branch of the Reformation is historically significant. On the one hand, the≪Consensus Tigurinus≫brought the unity of the Zwinglian Reformation and that of the Calvinist in Switzerland. This means to be a single Reformed Church. But on the other hand, the document was attacked by the Gnesio Lutheran Joachim Westphal, and it brought about the innocent occasion of the second sacramental controversy.
