Let me tell some brushstrokes of history on the fest of Corpus Christi for us, catholics.
The feast of the Corpus Christi dates back to the end of the 13th century thanks to the visions of St. Julian of Mont Cornillon (Belgium) and the well-known miracle of Bolsena.
Saint Juliana was the prioress in the abbey of Mont Cornillon, the center of a movement of Eucharist adoration from which come some customs as the bells during consecration. Since she was young Saint Juliana showed great veneration for the Blessed Sacrament and in her visions the Church, represented by a full moon, appeared with a black stain that meant the absence of a fest in His honor.
