I would like the Logos library to include The Faith of Jesus Christ in early Christian Traditions, by Ian G. Wallis.
It is referred to extensively in On Romans and Other New Testament Essays, by C.E.B. Cranfield when he discusses the dispute between the subjective vs. objective genitive interpretation in regard to the phrase 'πίστεως Ἰησοῦ'. Since this has become a topic of recent interest in the last 20 years and since the NET Bible discusses the matter in its translation notes it would seem that Wallis's work would constitute a valuable addition to the Logos Library.
