" When God saw that Abraham had not withheld his only son, he swore to bless all nations through Abraham’s seed (see Gn 22:15-22). Since the blessing of a father is reserved for his family, this oath is nothing less than God’s pledge to restore the human race as his own worldwide family. That is why the establishment of the Catholic Church must be attributed to God’s faithfulness and power. It represents nothing less than the historic fulfillment of God’s sworn covenant to Abraham.
