Basil of Caesarea : There should … be certain bones of the inner person in which the bond of union and harmony of spiritual powers is collected. Just as the bones by their own firmness protect the tenderness of the flesh, so also in the church there are some who through their own constancy are able to carry the infirmities of the weak. And as the bones are joined to each other through articulations by sinews and fastenings that have grown on them, so also would be the bond of charity and peace, which achieves a certain natural junction and union of the spiritual bones in the church of God. — HOMILIES ON THE Psalms 16:13 (Psalms 33) Jerome : Therefore, the prophet prophesies to the spirit, and says: Thus says the Lord God: Come, O spirit, from the four winds; come, that is, from the four corners of the world, so that just as in the first creation of man God breathed into his face and he became a living soul (Genesis 2:7), so in the second creation, that is, the resurrection of the dead, being breathed upon by the spirit, they may be brought to life again; for when the spirit entered the human bodies, immediately they lived, and stood upon their feet. — Commentary on Ezekiel
