As I have just enquired of Fr. Z over at What Does the Prayer Really Say? for advise on library matters I though I might extend that enquiry to my passing readership: Any suggestions for solid orthodox theological textbooks to build up a library. Ours is pretty good but has been neglected. We have a good scripture section, a full set of pre and ante-Nicene fathers, and a very good spirituality section. But there are holes and some stuff is out-dated and some stuff is just plain heretical (Kung, Schillebeekcx, etc).
So any suggestions appreciated!
