In his lifetime his more than twenty works sold well and he is certainly someone whose works look worth reading. What did for him then? Unlike Ryle he was no controversialist. in fact he kept right out of it and never identified with any party within or without the Church of England. Perhaps Spurgeon is responsible. In his Commenting and commentaries he quite sniffily dismisses Oxenden's contributions.
On Ruth - A very tiny affair, of no great moment to the expositor.
On Psalms - For reading at family prayers. Alas, poor families! Ye have need of patience.
To listen to these sermons must have afforded a suitable Lenten penance to those who went to church to hear them. There their use began and.ended.
The Gospels - Why Oxenden's books sell we do not know. We would not care to have them for a gift. "Milk for babes" watered beyond measure.
Our speaker begged to differ.
