Too many churches today have focused upon the worldly administration or the academics of doctrinal study without the actual spiritual mechanics involved, except by perhaps a handful.
The SAR crowd are easily distracted by a worldly Christian culture. Many who do advance to developing doctrine in their flock, tend to fall into academics rather than education,..teaching the soul, rather than obedience first through faith in Christ during their studies.
The SANR crowd frequently identify most churches as being 95% worldly and Christian culture in a less efficient format than gleaning doctrinal academics from other sources, but miss out on the spiritual benefits God has provided in the assembly of fellow spiritual believers.
In other words they sit in judgement on the organized churches as being "worldly" and then use that as an excuse not to assemble and learn from other Christians, and not to participate in the local ministry opportunities offered by the organized churches both local and foreign.
Every denomination and every church within that denomination has their own personality. Some are indeed dead, but most are alive and blessing their community and world with a variety of missions.
