The spelling (and date?) in the Jewish Expositor is a little different:

Prayer: Thank you, Lord, for men and women of faith, vision and scholarship such as McCaul, and the legacy they left for the generations that followed. Help us to build responsibly on their foundations, with appropriate contextualisation of their work. In Yeshua’s name and for his glory we pray, Amen.

`Alexander McCaul was Professor of Hebrew and wrote “The Old Paths”, a commentary on the Talmud which was frequently published in many languages by the London Society for the Promotion of Christianity amongst the Jews (CMJ).

This is the first recorded use of the term “Judaeo-Christian” which later comes to mean ‘within the tradition of Judaism and Christianity”, but here refers to a Jewish expression of the Christian faith. See (if you read Dutch_
