All,
Has anyone had experience with the Expository Preaching Movement, in general, and Creekside Bible Church, in particular?

Since joining, a relative of mine:

has come close to alienating every family member she ever had,

declaring she only got 'saved' after joining this group (despite testimonies and deep involvement at her childhood church)

Her husband's only conversations relate to preaching or protesting abortion clinics and finding faults with his brother-in-law's ministry, almost for the point of trying to be hurtful.

Rejecting all forms of birth control and getting pregnant as soon as she gives birth to the last child,

Rejecting the Christmas traditions she once loved and now finding any celebration 'sinful'.

Her husband is now deciding to go half-way across the country for an unaccredited affiliated seminary program.

My relative's complete personality change has been bizarre and we are concerned.
