(3) Various substitutes were made for the Catholic doctrine of transubstantiation, the idea that in the Lord's Supper the bread and wine by the word of the priest are actually changed into the Body and Blood of Christ. The Lutherans maintained what they called consubstantiation, that Christ was _with_ and _in_ the bread and wine, as fire is in a hot iron, to borrow the metaphor of Luther himself. The Calvinists, on the other hand, saw in the Eucharist, not the efficacious sacrifice of Christ, but a simple commemoration of the Last Supper; to them the bread and wine were mere symbols of the Body and Blood. As to the Anglicans, their position was ambiguous, for their official confession of faith declared at once that the Supper is the communion of the Body and Blood of Jesus Christ but that the communicant receives Jesus Christ only spiritually: the present-day "Low Church" Anglicans incline to a Calvinistic interpretation, those of the "High Church" to the Catholic explanation. (4) There were pronounced differences in ecclesiastical government. All the Protestants considerably modified the Catholic system of a divinely appointed clergy of bishops, priests, and deacons, under the supreme spiritual jurisdiction of the pope. The Anglicans rejected the papacy, although they retained the orders of bishop, priest, and deacon, and insisted that their hierarchy was the direct continuation of the medieval Church in England, and therefore that their organization was on the same footing as the Orthodox Church of eastern Europe. The Lutherans rejected the divinely ordained character of episcopacy, but retained bishops as convenient administrative officers. The Calvinists did away with bishops altogether and kept only one order of clergymen-- the presbyters. Such Calvinistic churches as were governed by assemblies or synods of presbyters were called Presbyterian; those which subordinated the "minister" to the control of the people in each separate congregation were styled Independent, or Separatist, or Congregational. [Footnote: This latter type of church government was maintained also by the quasi-Calvinistic denomination of the Baptists.] (5) In the ceremonies of public worship the Protestant churches differed. Anglicanism kept a good deal of the Catholic ritual although in the form of translation from Latin to English, together with several Catholic ceremonies, in some places even employing candles and incense. The Calvinists, on the other hand, worshiped with extreme simplicity: reading of the Bible, singing of hymns, extemporaneous prayer, and preaching constituted the usual service in church buildings that were without superfluous ornaments. Between Anglican formalism and Calvinistic austerity, the Lutherans presented a compromise: they devised no uniform liturgy, but showed some inclination to utilize forms and ceremonies.
