Using frequency of tongues-speaking as a spiritual credential is spiritually abusive; Mike refuses to disclose personal charismatic experiences in that context.

In some circles, speaking in tongues is treated as the credential that earns the right to be heard. When Mike debates hyper-charismatic claims with scripture, he is often asked "but do you speak in tongues?" - implying that a negative answer would invalidate his biblical analysis. Mike calls this spiritually abusive and refuses to participate in credentials-by-tongues-frequency.
