Francis denies Immaculate Conception, says Virgin Mary Not a Saint from the Beginning:
Our Lady and Saint Joseph are full of joy: they look at the Child Jesus and they are happy because, after a thousand worries, they have accepted this gift of God, with so much faith and so much love. They are “overflowing” with holiness and therefore with joy. And you will tell me: of course! They are Our Lady and Saint Joseph! Yes, but let us not think it was easy for them: saints are not born, they become thus, and this is true for them too.
