Orthodox baptism here, despite some “setbacks” during communist times

Commies lost the plot in USSR. Old-timers are saying people of USSR had to working during ‘subbotniki’ and ‘voskresniki’ (sundays) usually in spring.  It’s one day when people are encouraged to free work. On some occasions voskresniki were held on Easter day. Working on such an important religious celebration was not acceptable for religious people. Marrying in churches were a bit problem too due to condemnation at work.
