[32] Citing data from the Cooperative Congressional Election Study and General Social Survey, political scientist and statistician Ryan Burge noted that nondenominational Christians are very similar to Southern Baptists, but with some caveats.
On religious matters, both groups attend church at the same rate, yet nondenominationals are more likely to hold a moderate theological position on the Bible than SBC churchgoers.
He argues that nondenominationalism encourages a descent of Christianity—and indeed, all religions—into comfortable "general moralism" rather than being a focus for facing the complexities of churchgoers' culture and spirituality.
Prothero further argues that it also encourages ignorance of the Scriptures, lowering the overall religious literacy while increasing the potential for inter-religious misunderstandings and conflict.
[35] Presbyterian dogmatic theologian Amy Plantinga Pauw writes that Protestant nondenominational congregations "often seem to lack any acknowledgement of their debts and ties to larger church traditions" and argues that "for now, these non-denominational churches are living off the theological capital of more established Christian communities, including those of denominational Protestantism".
[37] Ryan Burge argues that nondenominational churches are less equipped to monitor or report sexual abuse cases because they lack national organizations to do so.
[38] In an article on evangelical clergy sex abuse in The New Republic by Elle Hardy, religious studies scholar Matthew D. Taylor argues that the relative lack of accountability in nondenominational churches attract pastors "who are more megalomaniacal and authoritarian in their personality”.
Since nondenominational churches lack a hierarchy to answer to, pastors with authoritarian personalities are given more opportunities to exert power and control over their congregants.
