Rabbi Paulus Elkana
Olarius, who wrote a preface to a Hebrew translation of the Augsburg confession prepared by Philipp Gallus in 1888, reports of Paulus, a rabbi in Prague who had been his teacher. The rabbi came to faith after reading the Hebrew translations of the Gospel of Matthew and Paul’s epistle to the Romans.
