Every year on 8 July the Orthodox Christians celebrate the Day of saints Peter and Fevronia. This holiday was originally religious, but in 2008 he officially received the status all-Russia day of family, love and fidelity.

One of the most pressing problems of theology has always been theodicy.

If He didn't create it, why it is there – because all things created by God.
