The Holy Spirit is a dimension of Godhood which is not given much attention, yet one that is critical for our spiritual development. In this work Richard Mullin shows how the contribution of American Philosophers at the turn of the 20th century can serve as a basis to reenvision theology. Importantly, he distinguishes the historical church with all its shortcomings and the Universal or "Beloved Community." Read this work if you are seeking a mature spiritual vision and one for which the church is a task that remains to be completed.
