"Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these speak Galilaeans? And how hear we every man in our own tongue, wherein we were born?" Acts 2:6-8.
That was a miracle at Pentecost, one of many. However, you don’t believe that every Christian liturgy or gathering is miraculously translated, do you?
