Letterism 

John Granville Woolley, Civic Sermons, 1911:

"The ignorant, dogmatic letterist may groan over the 'apostate church' and watch 
for the Lord to dishonor her and stultify Himself; but there is no 'apostate 
church.' The crowd that puts on its best clothes on Sunday and goes to meeting, the aggregate of the parish censuses, is not the church. But in that, there is the old, true church, unscathed and undiscouraged. She has held up Christ, straight through the centuries, and the crowd has come to her with many aims and many isms and many sins

Ernst Hofer, The Lariat, 1923 - "Greek letterism"

Richard M Edwards, Scriptural Perspicuity in the Early English Reformation in Historical Theology

The Antiochenes (literalist) opposed the Alexandrian School's (letterist) interpretive methodology founded on the Greek/Jewish allegorical interpretive methodology.

"Following the Babylonian captivity, the Jewish rabbis fell into the quasi-worship of even the letters of scripture, adopting 'letterism' as a springboard to allegorization and spiritualization. They committed the sin about which Paul later wrote: 'The letter kills, but the spirit gives life'. (2 Cor 3:6). To their credit, not all the rabbis fell into letterism or, later, allegory".
