even long after Constantine, in consequence of the discipline of secrecy, there was neither public exposition or procession of the B. Sacrament.  The faithful however adored it privately, as for instance, S. Gregory Nazianzen relates of his sister Gorgonia, that when seized by a fever “she fell down with faith before the altar, and invoked with a loud cry Him who is honoured thereupon”. (Discourse on her funeral).  S. Cyril of Jerusalem also exhorts the believer, that when he receives the chalice of the blood of Christ he should bow down profoundly and adore. (Catech. 5), The office and mass of Corpus Christi were composed by S. Thomas Aquinas.  As holy-thursday is in great part devoted to the sufferings of Christ, the festival of Corpus Christi with its procession was instituted about the middle of the thirteenth century by Urban IV at the petition of B. Juliana of Mount Cornelione, and in consequence of the miracle of Bolsena, well known as the subject of one of Raffaello’s frescoes in the Vatican.  See Bened.  XIV, De Festis, and the authors cited by him.  The miraculous corporal stained with blood is still preserved at Orvieto, the celebrated cathedral of which owes its foundation to the miracle.  “No one eats that flesh, says S. Augustine, unless he has first adored” in ps. 98 “The flesh of Christ,” says S. Ambrose “which we adore even now in the mysteries, and which the apostles adored in the Lord Jesus” (de Spir.  S. lib. 34, c. 12) All the fathers and liturgies mention this adoration, which was therefore derived from apostolic tradition.  Sala ad Bonae lib. 2, c. 13.]

[Footnote 68:  In the Greek church communion is on this day reserved for the sick of the ensuing year under the form of bread alone, according to Leo Allatius. (De utriusque Ecclesiae consensione).  Pope Innocent I in the beginning of the 5th century directs, that the eucharist be preserved on this day for the priest and the sick.  This reservation is mentioned also in the Gregorian sacramentary, without any mention of the sacred blood, since it might be spilt.  It has taken place in the Pauline chapel ever since its erection by Paul III.  A particle of the B. Sacrament was formerly preserved after mass on festivals and carried back in procession to the sacristy:  it was carried to the altar in procession on the next festival, and a portion or the whole of it was put into the chalice before the host was broken.  See Cancellieri, De Secretariis T. I, p. 217, seq.]

[Footnote 69:  These prelates used to refer cases and petitions to the Popes, as they now do the former to their tribunal, which according to Gonzalez derives its name of Segnatura from the signature of the sovereign affixed to its decree.]
