During Easter of 1570, in the Church of St. Erasmus in Veroli, the Blessed Sacrament was exposed (at the time, the Blessed Sacrament was first placed in a round pyx and then placed in a large chalice, covered with a paten) for the 40 hours of public adoration.
The child Jesus appeared in the exposed Host and manifested many graces. Today, the chalice where the Blessed Sacrament was exposed is kept in the same church of St. Erasmus and is used once a year at the celebration of Mass on Easter Tuesday.
At Easter in 1570, in the Church of St. Erasmus, the consecrated Host, according to the traditional rite at the time, was placed in a round silver container (pyx) and placed in a burse lace holder - this was later placed in a large ceremonial silver chalice with its paten; the whole wrapped in an elegant silk cloth.
It should be mentioned that at that time exposition of the Blessed Sacrament in a monstrance was not a widespread practice even though the Council of Cologne (1452) specifically referred to the monstrance.
It was the custom for each civil confraternity to be present for an hour of adoration before the exposed Blessed Sacrament. It was at one of these hours of adoration which had the members of the Confraternity of Mercy (which predated both the Confraternity of Corpus Christi and of our Blessed Lady) vested in their black robes and kneeling in prayer.
The most authentic document about the Eucharistic miracle was taken immediately by the chancery; it is preserved in the archives of the Church of St. Erasmus. The detailed deposition and account of the miraculous event is given by a Giacomo Meloni who was among the first witnesses.
His testimony follows: "Raising my eyes towards the chalice, I saw a most brilliant star at the base of the chalice's cup and above the star, the Blessed Sacrament in the size of the host used by the priest at Mass. The star was attached to the Blessed Sacrament (...).
The vision ended when small children in adoration, similar to small angels, were seen around the sacred boat... To this day, this miraculous event is commemorated with solemn ceremony in the presence of the bishop.
The chalice, its paten and the silver pyx where the blessed sacrament was exposed, have all been preserved and they remain with the relics/ reliquaries of the saints. The sacred species (the consecrated bread) of the miraculous Host of Veroli was consumed after 112 years.
In 1970 on the occasion of the 4th centenary of the miracle, the 3rd Eucharistic Congress of the Diocese of Veroli-Frosinone was celebrated. The adoration of the Blessed Sacrament takes place every first Friday of the month, with all other churches being closed (...).
