Agape, if you want to study the Bible texts, unlike the Watchtower you must think about why the particular piece was written, who wrote it, where, when and for what purpose? Just one example:
Why was the early Christ sect discussing the problems of feeding the followers from which later readers interpret a faithful and discreet slave as being a ”class” by divine appointment? By looking at what religions did at that time it is found that they supplied meals for the members, who would contribute money for the common pool if they could, to fund such activities. The presbyteroi (elders) who might have collected the money and given it to the episcopoi (bishops) would have been troubled by those who just came for a free lunch... and the church then was predominantly for the poor. The poor, being canny, would go to any and every cult providing meals so the episcopoi would have asked the rhetorical question “Who is the faithful and discreet slave which his master gave over all his belongings” to get the attendees to imagine that the poser of the question belonged to the ones chosen by God. Cult loyalty was everything.
The Greek scriptures are about the struggles of the Pauline-Jesus religion jockeying for market dominance. They have no prophetic meaning at all but the language and talk is “cultic” and apocalyptic which is why the WTBTS still use that old discussion to further their own influence and membership numbers today.
Most of the Bible is borrowed from paganism... around eighty three per cent is neither original text nor original story. Jesus is not original. The story of a fictional character exactly fulfilling the role ascribed to Jesus began many centuries if not millennia before the start of our calendar.
One of the best ways to determine historical truth is to see what people were doing, saying and believing at the time period in question, the science of this aspect of history is sociology.
Someone who took this (sociological) viewpoint and the end of the nineteenth century was JM Robertson and one of his books which should be read by all Bible students is A Short History of Christianity. Another relevant book, of which there are many titles on the same theme is Christianity Before Christ by John G Jackson (ISBN: 9870910309202) AAPress.
I wish you well with your Bible studies.
