MB recommended that I read this piece by Bishop Hilarion Alfeyev: Christ the Conqueror of Hell,
The Descent of Christ into Hades in Eastern and Western Theological Traditions

I found this old posts at De Unione Ecclesiarum:
Garrigues on the Father
Garrigues on Latin trinitarianism

Apparently Fr. Garrigues left the Dominicans for a while; he was attached to the Pontifical Theological Academy in 2007, but I do not know if he is still there now.
