Bede, on Gen 22:18

“And in thy seed shall all the nations of the earth be blessed, because thou hast obeyed my voice.”

“For, in all humility, we too belong among those descendants of whom it was said that it shall be an everlasting law for him and for his descendants throughout their generations. We are not born of the lineage of Aaron, but we have believed in him in whom Aaron also, with the saints of that age, believed. Concerning him, it was promised to Abraham that in "in your descendants all the families of the earth shall be blessed."”
