It may be that in the course of history certain dimensions of saving truth become obscured and must be recovered but it is impossible for a theologian to stand apart from tradition and begin his work ab initio; to do so would be to cut himself off from the Church, which is the source sine qua non of theology, and to deny
the historical givenness of Revelation.
The
givenness of the barrier between time now and time then yields for us banalities about anachronism, on the one side, and imposes upon us the requirement of mediating between
historical fact and religious truth, on the other.
