"He could not be our 'Jesus' (God-Saviour) unless He were 'the Christ'; for He could not reveal the way of salvation, except He were a prophet: He could not work out that salvation, except He were a priest: He could not confer that salvation upon us, except He were a king: He could not be prophet, priest, and king, except He were the Christ."  John Pearson
