 Toward the middle of the 16th century, the Reformed began to commit their beliefs to confessions of faith, which would shape the future definition of the Reformed faith.The 1549 "Consensus Tigurinus" brought together those who followed Zwingli and Bullinger's memorialist theology of the Lord's supper, which taught that the supper simply serves as a reminder of Christ's death, and Calvin's view that the supper serves as a means of grace with Christ actually present, though spiritually rather than bodily.The document demonstrates the diversity as well as unity in early Reformed theology.
