History has it that, during the journey of Mary and Joseph to Egypt as instructed by the angel(Mathew 2:13), when King Herod was carrying out the massacre on every newborn baby, they stopped by at the Grotto to feed their baby (Jesus).
Drops of milk from Mary’s breast fell on a red rock which became white in an instant and ever since then, the Grotto has become a sacred place.
This was due to the impact of the milk, which was believed to be righteous virgin milk, and since then new mothers and women go there to pray to God for fertility.
The Grotto also features the image of Mary popularly referred to as “Our Lady” breastfeeding Jesus, as well as the Marian shrine, and the monastery.
It is believed that mixing the white chalk present in the grotto with one’s food coupled with praying to mother Mary, will cure infertility problem.
It had become a place to turn to when people’s hope in doctors or science on fertility had been dashed, and over the years it has been serving this purpose based on the testimonies of those who have tried it out.
Also, brother Lawrence (an occupant of this building) had witnessed that over 4000 couples have benefited and earn fertility through this sacred milk Grotto.
