Come all ye faithful

"Adeste Fideles" is a hymn tune attributed to English hymnist John Francis Wade (although the exact authorship is unknown and disputed). The text itself has unclear beginnings, and may have been written in the 13th century by John of Reading, though it has been concluded that Wade was probably the author.
The original four verses of the hymn were extended to a total of eight, and these have been translated into many languages many times, though the English "O Come All Ye Faithful" translation by the English Roman Catholic priest Frederick Oakeley is particularly widespread.
