It often happens

“It often happens that if the Scriptures prescribe something which is contary to the practice of those who hear it, they treat is as a figurative expression. Likewise, if some erroneous notion has gotten into our minds first, regardless of what Scripture has asserted, men will think it is figurative.”

St. Augustine, De doctrina Christiana 3.10, quoted in Martin Chemnitz, The Lord’s Supper (CPH, 1979), p. 76.
