John 17:20
I ask not only on behalf of these, but also on behalf of those who will believe in me through their word — The prayer's scope expands beyond the Twelve to encompass all future believers, including the Johannine community and beyond. "Through their word" (dia tou logou autōn, through their message) establishes the disciples as instrumental in transmitting faith, emphasizing the role of apostolic witness. This verse envisions the Church's missionary expansion as the fruit of the disciples' faithful testimony.
