Ancient people experienced hearing loss and speech difficulties for many of the same broad reasons people do today, including conditions present from birth, illness, injury, and problems affecting the ears or speech. Ancient descriptions, however, rarely provide enough information to identify a precise modern diagnosis.
First-century medicine had only limited means of understanding or treating serious hearing and speech disorders. Because everyday communication was overwhelmingly personal and oral, substantial hearing loss could affect many areas of life.
A person who could not hear well might depend upon gestures, observation, familiar routines, and the assistance of relatives or friends. Difficulty speaking could further complicate communication with people outside the household.
Most causes of deafness and speech impairment leave little recognizable archaeological evidence. Physical remains can occasionally reveal disease or injury affecting the skull or ear region, but archaeology usually cannot determine whether an individual was deaf.
Biblical and other ancient writings refer to people who were deaf, unable to speak, or had difficulty speaking. These descriptions establish the presence of such disabilities without normally identifying their medical cause.
The Old Testament commands respect for people with disabilities, including the instruction not to curse the deaf. Prophetic descriptions of restoration also include the deaf hearing and those unable to speak rejoicing with their voices.
Mark describes Jesus healing a man who was deaf and had difficulty speaking. Jesus takes him aside, and after the healing the man is able to hear and speak plainly. Other Gospel passages also include deafness among conditions overcome through Jesus' ministry.
Hearing and speech disabilities were recognized in antiquity and could create substantial practical difficulties in an overwhelmingly oral society.
We generally cannot determine whether a particular Gospel description resulted from congenital deafness, infection, injury, neurological disease, or another condition.
Restoring hearing and speech meant more than correcting a physical problem. It could greatly increase a person's ability to communicate, participate in conversation, and interact independently with the surrounding community.
