Factual error: Jehovah is spelled Iehovah in Latin. However medieval languages (Latin or vernacular) had neither official rules nor the letter 'J'. It was not until the sixteenth century that the French humanist Pierre de la Ramée proposed to use the 'J' as a separate letter distinct from the 'I'. The 'J' could therefore not have been a trap at the time the test was constructed. (01:46:20)
Suggested correction: The concept of what looks like a "J" was sometimes used when writing numbers in Roman numerals, originating sometime in the Middle Ages. While "J" did not exist as a letter at that time, what visually looked like a "J" did exist at the time the Trial was made. The purpose is to weed out those who can't spell the word of God...there's nothing implying that whoever created it meant for all the tiles to be understood as just letters.
