And you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength: this is the first commandment.
Read Chapter 12
Basil the Great
AD 379
It is not the privilege of any chance person to go forward to the perfection of love and to learn to know him who is truly beloved, but of him who has already “put off the old man, which is being corrupted through its deceptive lusts, and has put on the new man,” which is being renewed that it may be recognized as an image of the creator. Moreover, he who loves money and is aroused by the corruptible beauty of the body and esteems exceedingly this little glory here, since he has expended the power of loving on what is not proper, he is quite blind in regard to the contemplation of him who is truly beloved. Exegetic Homilies, Homily
The expression, “with the whole,” admits of no division into parts. As much love as you shall have squandered on lower objects, that much will necessarily be lacking to you from the whole. Exegetic Homilies, Homily
Human life consists in a threefold unity. We are taught similarly by the apostle in what he says to the Ephesians, praying for them that the complete grace of their “body and soul and spirit” may be preserved at the coming of the Lord. We use the word “body,” for the nutritive part, the word for the vital, “soul,” and the word “spirit” for the intellective dimension. In just this way the Lord instructs the writer of the Gospel that he should set before every commandment that love to God which is exercised with all the heart and soul and mind. This single phrase embraces the human whole: the corporeal heart, the mind as the higher intellectual and mental nature, and the soul as their mediator.
And that we ought to worship God alone, He thus persuaded us: "The greatest commandment is, Thou shalt worship the Lord thy God, and Him only shall thou serve, with all thy heart, and with all thy strength, the Lord God that made thee."
