are bishops in the bible?
"The "elders" (Greek, presbuteros) or "bishops" (episkopos) were the most important officers of the church. The term elder means older one, implying dignity and respect. ... The term bishop means "overseer." Paul used these terms interchangeably, equating elders with overseers or bishops (Acts 20:17,28; Titus 1:5, 7).
