The Feast of St. Elizabeth
is today. There is information on her here

"More blessed was Mary," says St. Augustine, "in receiving Christ's faith, than in conceiving Christ's flesh;" and St. Chrysostom declares, that she would not have been blessed, though she had borne Him in the body, had she not heard the word of God and kept it. This, of course, is an impossible case; for she was made holy, that she might be made His Mother, and the two blessednesses cannot be divided. She who was chosen to supply flesh and blood to the Eternal Word, was first filled with grace in soul and body; still, she had a double blessedness, of office and of qualification for it, and the latter was the greater. And it is on this account that the Angel calls her blessed; "Full of grace," he says, "Blessed among women;" and St. Elizabeth also, when she cries out, "Blessed thou that hast believed."
