Perhaps you should try some spelling variations:
matthew xxviii » matthew xxii, matthew xiii, matthew xxv
matthew xxiv » matthew xxv, matthew xxii
matthew xvi » matthew xxii, matthew xxv
2f sermons » 21 sermons, 24 sermons, 20 sermons
2c 51 » 24 51, c 51, 21 51
20 51 » 290 51, 20 21, 24 51

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %2f ((matthew xxviii) OR (((matthew xxiv) OR (matthew xvi))))%((2c 51) OR (20 51)) %((2f sermons) OR (2 sermons)) %2 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((matthew xxviii) or (((matthew xxiv) OR (matthew xvi))))%((2c 51) or (20 51)) %((2f sermons) or (2 sermons)) %2 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((matthew xxviii) or (((matthew xxiv) OR (matthew xvi))))%((2c 51) or (20 51)) %((2f sermons) or (2 sermons)) %2 early works to 1800%22*.
