The True Spouse of Jesus Christ - St. Liguori
The true spouse of Jesus Christ is a work written to the nuns under St. Liguori's care. In the work he gives detailed instructions about the way to spiritual perfection.
The work reveals the rich knowledge St. Liguori (1696–1787, Catholic Bishop) has of scripture, the writings of the church fathers and the saints of the church. He literally seems to breathe the moral doctrine of the church into words. The epic work is an excellent resource for those seeking to advance in spiritual perfection.
