I wish your Canadian Reformed brothers would translate more of this type of material. What I have read out of your circles has been worthwhile. It is just not widely circulated in the broader reformed community.
I wonder if part of the explanation for this phenomena is Schilder's view of ecclesiology; to which you have alluded in the past.
I would second the vote for J.C. Ryle. His three volumes on John are excellent, and much deeper than his works on Matthew and Mark. I am told he wrote first for his parishoners, seeking to encourage them to read the word for themselves. As his writing progressed, he saw more demand and realised that he had the opportunity to write a lot more - hence his commentaries on Luke and John contain a lot more than Matthew and Mark.
