Though St. Joseph knew nothing of fetal microchimerism, God continued to bless him with the presence of Jesus whenever he was in the presence of his wife. To be near Mary is to be near Jesus. Jesus lives in her! Mary has in her body some of her divine Son’s living cells. Our Lord didn’t need to be in the house for St. Joseph to remain in the presence of God. Wherever Mary was, Jesus was. Saint Joseph’s wife is a living tabernacle, a walking monstrance, a veiled temple. No wonder demons do not dare come near Mary — she is never without the divine presence. God lives in her body!
