...whoever is guided solely by his own judgment and decision will never climb up to the summit of perfection and will not fail to be the victim of the devil's ruinous power to delude.

God is not only to be known in His blessed and incomprehensible being, for this is something which is reserved for His saints in the age to come. He is also known from the grandeur and beauty of His creatures, from His providence which governs the world day by day, from His righteousness and from wonders which He shows to His saints in each generation.

...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'.

...we know that God arranges the opportunities for salvation in different ways. Our situation is that we respond eagerly or in a laggardly manner to these opportunities made available by God to us. God made the call come out of your homeland; Abraham by coming out was exercising obedience. There was the instruction come into the land; it was done, and that was the work of obedience. But the addition which I shall show you has to do with the grace of God, who gave a command - and a promise.

Everything we do, our every objective, must be undertaken for the sake of... purity of heart... we must practice the reading of the Scripture, together with all the other virtuous activities... to hold our hearts free of the harm of every dangerous passion and in order to rise step by step to the high point of love.

[God] arranged that the boy Samuel should be chosen but instead of teaching him directly He had him turn once or twice to an old man. This youngster, to whom He had granted a direct encounter with Himself, had nevertheless to go for instruction to someone who had offended God, and all because that person was an old man. He decided that Samuel was most worthy of a high calling and yet He made him submit to the guidance of an old man so that once summoned to a divine ministry he might learn humility and might himself become for all the young a model of deference.

The Doctor of our souls has placed the remedy in the hidden regions of the soul.
