Changes in pastoral practice indicate changes in understanding of doctrine:
The fact of the matter is that any doctrine that is not upheld is worthless. It becomes a doctrine that we are not willing to practice and, therefore, a doctrine that we do not really believe. That is where the PCA is at this time in her history. By these judicial decisions that elevate church polity above theology, the court is officially saying that she is not willing to decide between justification by faith alone and legalism; that she is not willing to reject the teaching of baptismal regeneration; and on and on.
Changing doctrine is better than ignoring doctrine. Ignoring doctrine is a bigger change than changing doctrine.
