The gospels give us a clear picture of Jesus’ activity at Capernaum, what he did on the lakeshore and in particular in the synagogue and in the house of "Peter and Andrew" (Mark 1: 29). The evangelist Mark sheds more light on Peter’s house. After proclaiming the parables and other teachings to the crowds nearby at Tabgha, place of the "public teaching", Jesus would give the "private teaching" back at Peter’s house: "To you has been given to know the mystery of God’s kingdom; but to those outside everything is told in parables" (Mark 4: 11).
They are the walls of this very house which divided those who were outside from those inside who sat at Jesus’ feet and listened, and in particular the walls of the principle room in the house, who separated it from the ordinary life of Peter’s family and made it a church, a meeting place for proclaiming the Gospel and for prayer and adoration. Again in Mark’s gospel, chapter 3, we watch as it is acted out the early formation of the Church. Jesus’ own people come from Nazareth, his mother and his brothers. Those who have come to listen to him are crowded together in the main room and courtyards of the house while his family are outside trying to find him. Jesus says: "Who is my mother and who are my brothers?" Looking around at those inside listening he adds: "Those who do the Father’s will are brothers, sisters and mother to me". The guests in Peter’s house are already part of his family and members of the new family belonging to God the Father.
When in 1968 the excavations at Capernaum began again, an area was noted "sacred" because it included the house of Peter. The remains of an octagonal, fifth-century church had been uncovered in 1921. Once the mosaic floor had been removed and the entire area excavated, the team of archaeologists identified three principal strata along with many other, intermediary levels indicating periods of habitation: the first stratum was of private houses built during the second century B. C. and in use until the fourth century A. D.; the second stratum was the "house of the chuch" (Domus-ecclesia) with adaptations for cultic use; the third stratum was the octagonal church form the fith century A. D. Peter’s house was close to the lake-shore and flanked to the east by the principle, north-south road of the village. It was built just like the other houses - little rooms with roofing grouped around largish, open courtyards. The archaeologists naturally focused their attention on this house of particular interest. They were able to find overlaying levels of habitation dating from the late-hellenistic period. From the second half of the second century B. C. up until towards the end of the first half of the first century A. D. these levels are made up of layers of beaten earth mixed with household, ceramic objects (fragments of jars, pots, plates and lamps). Over the top of these older layers they uncovered something exceptional. Covering an area of roughly 12 square metres along the north-east side of the room which had been venerated was the flooring of at least six layers of white plaster. As well as this find, they gathered up various fragments of colored plaster which had certainly been used to decorate the walls of the room. At the same time it was remarked the almost complete absence of household-pottery fragments. Finally one should note that in all of the village of Capernaum, of which a great part has been excavated, this is the only room which has plaster on the walls and floor. All this points to the conclusion that Peter’s house, containing the room which was venerated, had already been set apart as a meeting-place for the community by the second-half of the first century A. D.
Concerning the transformation of Peter’s house into a Domus-ecclesia, has come down to us the precious testimony attributed to an already well-known pilgrim to the Holy Land, Egeria, writing towards the end of the fourth century: "And in Capernaum, what is more, the house of the prince of the apostles (Peter) has been turned into a church, leaving its original walls however quite unchanged". The archaeological diggings are proof of the accuracy and faithfulness of the above description.
Towards the second half of the fifth century the "insula sacra" was totally covered over by Byzantine builders who put up a church on an octagonal design. It is interesting to note that they must have had in mind to keep alive the memory of Peter’s house, because they built the centre octagon of their church right over the venerated room. The anonymous pilgrim of Piacenza passing through Capernaum around 560-570 A. D. writes about this final transformation: "And so we came on to Capernaum to the house of Saint Peter, which is now a basilica".
During the centuries which followed, Capernaum was abandoned and in time forgotten so that even the memory of where it stood was lost. But Capernaum was reborn a century ago with the arrival at the spot in 1894 of the Franciscans of the Custody of the Holy Land. The Memorial which stands today aims to conserve and protect the venerable ruins of the place where Peter opened his home to the Teacher from Nazareth. At the same time it seeks to offer to the many Christian pilgrims visiting Capernaum the chance to celebrate the communion there at Peter’s house in the town where Jesus declared: "I am the bread which has come down from heaven" (Jn 6: 41).
