The photo is from yesterday's celebration of Theophany in the provincial city of Kiev Vyshhorod, located on the right bank of the Dnieper, just 18 kilometers from Kiev.
Also note that the 'frozen' priest, Bishop Dimitrios Ntenisenko, celebrated the blessing of the water in a temperature of 20 degrees below zero.
Finally, the cold did not prevent Ukrainians from breaking the ice in a cross formation and dive into icy waters to be blessed.
