The Greek adjective archieratikos derives from archiereus (high priest, G749) and means 'belonging to the high priest' or 'high-priestly.' It appears once in the New Testament, describing the inner circle of the high-priestly family who interrogated Peter and John after the healing of the lame man.
The 'high-priestly family' (archieratikos) in Acts 4:6 represented the most powerful religious establishment in Jerusalem. Yet before this very group, Peter and John — unschooled, ordinary men — spoke with such boldness that the council 'could see that these men had been with Jesus' (Acts 4:13). The encounter illustrates the irony of the gospel: the most educated and powerful religious institution of its day could not silence two fishermen filled with the Holy Spirit. Institutional authority, however impressive, cannot prevent the advance of the kingdom. Proximity to Jesus transforms ordinary people into extraordinary witnesses.
