It is still possible today to see the miraculous imprint left by the Host which fell on the steps of the altar in the Caetani Chapel of Santa Pudenziana Church in Rome. The imprint on the step was left when the Host fell from the hands of a priest, who, while celebrating Mass was taken with doubt on the Real Presence of Christ in the sacrament of the Eucharist.
Santa Pudenziana is one of the oldest churches in Rome. According to a great number of historians, the Roman Senator Pudente gave hospitality to the Apostle Peter in his home, which stood exactly where the church's foundation lies. The name of the church is said to derive from the name of the Senator's daughter:
Pudenziana
and her sister Prascede, although never martyred, became famous because they wiped off the blood of martyrs after their execution. The church is adorned by numerous Roman mosaics from the early Christian era and was constructed in 145 A.D. on the site where there stood the house of Senator Pudente, according to the wishes of his daughters Prascede and Pudenziana. On the altar steps of the Caetani
Chapel, constructed by the Caetani family, to this day there is the imprint and the stain of Blood left by a Host which fell from the hands of a priest while celebrating the Mass.
The man was overtaken by doubts about the Real Presence of Jesus in consecrated Host, and immediately after the consecration, he inadvertently let the Host fall to the ground, where the imprinted mark is still visible today.
