Some languages make a distinction between the formal form of "you" and the informal form of "you." This page is primarily for people whose language makes this distinction.
In some cultures people use the formal "you" when speaking to someone who is older or in authority, and they use the informal "you" when speaking to someone who is their own age or younger or who has less authority. In other cultures, people use the formal "you" when speaking to strangers or people they do not know well, and the informal "you" when speaking with family members and close friends.
* Translators who use a source text in a language that does have formal and informal forms of "you" will need to understand how those forms are used in that language. The rules in that language may not be exactly the same as the rules in the translator's language.
>So it seemed good to me also, because I have accurately investigated everything from the beginning, to write an orderly account for <u>you</u>, most excellent Theophilus, so that <u>you</u> might know the certainty of the things <u>you</u> have been taught. (Luke 1:3-4 ULB)
Luke called Theophilus "most excellent." This shows us that Theophilus was probably a high official to whom Luke was showing great respect. Speakers of languages that have a formal form of "you" would probably use that form here.
This is part of a prayer that Jesus taught his disciples. Some cultures would use the formal "you" because God is in authority. Other cultures would use the informal "you" because God is our Father.
