Fr. Gabriel often visited people who had different religious views. He tried to share grace with everyone and lead them to the true faith. He says himself:
"Once, dressed as I was in my monastic schema, I went to the Synagogue. At the entrance hung a large portrait of Moses. I venerated it. The attendees liked this. Moses was a great prophet and I gave him his due respect. I had entered as they were reading from the Bible. Few were there and they looked at me with surprise. I began to preach, and when they heard about Christ they called for their High Priest. He came out but he did not stop me. Afterwards he invited me into his office. He listened with great interest and attention to what I said about Christ. Finally, he thanked me and we bid farewell.
