Who cares about tradition, this is according to scripture ( except the date, I guess).
It sounds like a lovely trip.
About 40 years ago we had a priest lent to our parish in Oakland, CA from the nation of Malta. As he explained to me, there were (at that time) too many priests in Malta so many of them went to other nations to serve. They returned to Malta as openings arose.
I can’t remember his name, but he was a kind and gentle man and he played the violin beautifully. This was just at the time that the Vatican II changes were being implemented and the Mass was first said in English. He wrote a beautiful Gloria and gave it to our Parish (St. Leo’s) to sing, copyright free.
St. Luke refers to the natives of the island as "barbarians" (barbaroi). If the island was Malta, they may have been speaking the Punic language, which was similar to Hebrew--would people St. Paul could have conversed with been called "barbarians"?
I don't think this counts as an infallible pronouncement that the Melite of St. Paul's shipwreck was Malta.
