I wanted to get a list of arguments that illustrate how the Watchtower Society is or isn't following 1st century christianity today.
WTBTS publications exemplify what Pinytus criticized during the second century (according to Eusebius, Book IV, chapter 23--emphasis is mine):
"Pinytus, replying to this epistle, admires and commends Dionysius, but exhorts him in turn to impart some time more solid food, and to feed the people under him, when he wrote again, with more advanced teaching, that they might not be fed continually on these milky doctrines and imperceptibly grow old under a training calculated for children."
