137 Those moralizers who want to keep a tight rein on God’s mercy and grace might claim that Therese could say this because she was a saint, but a simple person could not say the same. In that way, they excise from the spirituality of Saint Therese its wonderful originality, which reflects the heart of the Gospel. Sadly, in certain Christian circles we often encounter this attempt to fit the Holy Spirit into a certain preconceived pattern in a way that enables them to keep everything under their supervision. Yet this astute Doctor of the Church reduces them to silence and directly contradicts their reductive view in these clear words: “If I had committed all possible crimes, I would always have the same confidence; I feel that this whole multitude of offenses would be like a drop of water thrown into a fiery furnace”.
