Yes, there are English-speaking churches in Panama because professional people, which includes the clergy, often speak English. They are not all Panamanian. You have a lot of clergy in many of the religious faiths coming from other places. And so while Spanish is spoken, Hebrew is spoken of course in the synagogues, and English.
