The education of the Pharisees was refuse to Paul.
He could get a job as a lawyer (elder) to their laws.
As a believer or Messiah, he couldn't take that career.
His former training with the best teachers of the Jews,
left him at a disadvantage in the job market in his later years.
The apostle Paul was talking about a religious education!
What if a religion today condemn work related training,
in favor of denominational indoctrination? _______________.
Those listening to that religion would; stay captive to it,
have limited job choices, and be too poor to get educated later.
WT theology is the refuse, yet "the way" to GOD is biblical truth;
being clean, smart, and spiritual will get us close to Him.
The disciples weren't unlettered as to work training,
but unlettered in an education of the Pharisaical schools.
They had job skills to support their families and fellow believers.
WT just wants poor followers that can't think for themselves,
to be too broke - to be distracted from meetings, and
depressed enough to donated their last dollar to WTBT$ publishing!
Being a WT publisher is refuse, it's obedience to religious laws.
It's all a twisting of the scriptures, and manipulation of the mind,
to steal away the soul from GOD and family. Love less, all but WT.
