Death is a difficult subject in any language, I think. In English, you can say "died" indirectly by only using past tense of "be". Like "This was my friend. His name was Tom. He was a teacher." Some people might pick up on the subtlety, maybe.

The statements are very cryptic in nature. 1 probably means to be made available to the public. 2 and 3 seem to be some allusion to the bible. 2 may mean something like "living" are those who understand and "dead" are those who don't understand? but it is very hard to understand. 3 "to those who would bear witness to us" is very biblical. It was a phrase used by the Apostles. Again, it's very hard to understand, even to people who are native English speakers. Good luck!
