...Abraham, great Patriarch though he was, was justified by faith, and offered a strange victim (Gen 28:2), the type of the Great Sacrifice. Yet he saw not God as God, but gave Him food as a man (Gen. 18:2). He was approved because he worshipped as far as he comprehended.
St. Gregory Nazianzen (Second Theological Oration no.18)
In two things then was Abraham victorious: that he killed his son although he did not kill him and that he believed that after Isaac died he would be raised up again and would go back down with him. For Abraham was firmly convinced that He Who said to him, 'through Isaac shall your descendants be named,' was not lying.
