There is a saying ‘you cannot fight nature’, two catholic nuns have just proven that as they mysteriously fall pregnant during a missionary work they were assigned to do in Africa.

According to the catholic church, those having special ministries like fathers, nuns and bishops are not allowed to marry according to the vows they make when accepting such ministries, hence it will be regarded as odd if a nun is found pregnant.

Meanwhile, the church is investigating two nuns returned from missionary work pregnant.

The two women one a mother superior are from two different orders in Sicily.

Both nuns are African and were posted to their home continent as part of their charity mission.

One of the women, who is 34, only discovered she was pregnant when she had a medical scan after complaining of stomach pains.

The mother superior, whose age is not known, is based at an institute that helps “fallen women and their children.”

A church source in Rome said: “There is consternation at this news. It appears that both women were back in their home nations and obviously had some form of se_xual encounter.

An investigation has been launched. They both breached strict rules of chastity but the welfare of their children is uppermost.

“The most likely outcome is they will leave their religious service.”
