I doubt Stanton will let the money leave Texas. He may be planning to use it for legal fees when TEC comes after him.
As to the size of this church, nothing holds it back in growth. If not for being a part of ECUSA it would have 4 or 5 thousand members. They have a HUGE property and three services each Sunday in their main sanctuary with a smaller 250 person chapel available if needed. They preach the Gospel and bring people to Christ. Did I mention that they started a mission church 30 miles north and it now has 250 members? They know how to grow the faith and it is not about inclusion but about the Gospel.
