The first Common Prayer Book of Edward VI. enjoins unleavened bread to be used throughout the whole kingdom for the celebration of the Eucharist. It was ordered to be _round_, in imitation of the wafers used in the Greek and Roman Churches; but it was to be _without all manner of print_, the wafers usually having the impression either of a crucifix or the Holy Lamb; and _something more large and thicker_ than the wafers, which were the size of a penny. This rubric, affording matter for scruple, was set aside at the review of the Liturgy, in the fifth year of King Edward; and another inserted in its room, which still exists, by which it is declared sufficient that _the bread be such as is usually eaten_. It was the custom in Westminster Abbey, and in the Royal chapels, and the practice of such men as Bishop Andrewes, to use wafers, but ‘for peace sake,’ where wafers were objected to, plain and pure wheaten bread was allowed. It has been decided by the Privy Council that it not only may, but must, be common bread; the Injunctions, according to them, being of no validity against the rubric; while the Advertisements, having been made under Act of Parliament, and not contrary to the rubric, are an indication of its meaning—_i.e._, of the word ‘retained in the Ornaments rubric.’ The bread now used is common wheaten bread in most Protestant Churches. In some Presbyterian Churches a special kind of wafer is prepared for the purpose. In the Roman Church thin wafers are used. In the Eastern Churches they are of different sizes and thicknesses. They are thus classified by the Rev. F. E. Brightman in _Liturgies Eastern_: 1. Byzantine; a round leavened cake 5 × 2 in., stamped with a square (2 in.); itself divided by a cross into four squares in which are severally inscribed IC, XC, NI, KA. 2. The Syrian Jacobite and Syrian Uniat; a round cake, leavened with the holy leaven, 3 × 3/4, stamped like a wheel with four diameters (the alternate radii being cut off half way from the circumference by a concentric circle). 3. The Marionite; the Latin unleavened wafer. 4. The Coptic; a round leavened cake, 3-1/2 × 3/4, stamped round the edge with the legend, Αγιος ο θεος, αγιος ισχυρος, αγιος αθανατος, and within with a cross consisting of twelve little squares, each of which and the remaining spandrels are marked with a little cross placed diagonally. 5. The Abyssinian; a flat round leavened cake, 4 × 3/4, stamped with a cross of nine squares with four squares added in the angles of the cross. 6. The Nestorian; a round leavened cake, 2 × 1/2, stamped with a cross-crosslet and four small crosses. 7. The Armenian; a round unleavened wafer, 3 × 1/8, stamped with an ornamental border, the crucifix and the sacred name and sometimes with two diameters at right angles to the back.
