Lay hands hastily on no one, neither be a participant in other men's sins. Keep yourself pure.
Neither be partakers of other men's sins ... This warns that the person responsible for appointing elders who prove unfaithful is, in a sense, partaker of their sins, unless due deliberation, investigation and testing preceded such unfortunate appointment.  However, the share of the sins of others is not borne by the minister who properly observes these restrictions, restraints and precautions.  The same applies to the presbytery itself in the normal situation where they name additional elders to aid in the guidance of the church.
