My son has left the Church and now follows a progressive Baptist church. He seems to be following the teachings of Adam Hamilton. Does anyone know anything about him?
Do you mean Adam Hamilton, the liberal United Methodist minister?
You can find out about him here, adamhamilton.org
Seems to be typical of the progressive sides of the United Methodists.
There are progressive Baptist congregations, but this is not one.
Has your son told you why he left the Church? That’d be a good starting point.
