But you be not called Rabbi: for one is your Teacher, even Christ; and all you are brothers.
Read Chapter 23
George Leo Haydock
One is your master, or teacher, who is the Christ, and under him one vicar, the successor of St. Peter, with whom all Catholic teachers are one, because they all teach one and the same doctrine in every part of the Christian world; whereas in the multiplicity of modern sects, which are every day dividing and subdividing into fresh sects, no two leaders can be found teaching in all points exactly the same tenets; as each is not only allowed, but expected to follow his own private spirit, and to build his creed upon his own interpretation of Scripture.
