The key details are that he has normal speech and language development according to his parents, but is selectively mute in unfamiliar social situations like school and church. This history is most consistent with selective mutism, which is a disorder where children have normal speech abilities but do not speak in certain social situations due to anxiety.

Child abuse and normal development do not explain his symptoms.E: Selective mutism
