" The root destruction of religion in the country, which throughout the twenties and thirties was one of the most important goals of the GPU-NKVD, could be realized only by mass arrests of Orthodox believers. Monks and nuns, whose black habits had been a distinctive feature of Old Russian life, were intensively rounded up on every hand, placed under arrest, and sent into exile. They arrested and sentenced active laymen. The circles kept getting bigger, as they raked in ordinary believers as well, old people and particularly women, who were the most stubborn believers of all and who, for many long years to come, would be called 'nuns' in transit prisons and in camps.
True, they were supposedly being arrested and tried not for their actual faith but for openly declaring their convictions and for bringing up their children in the same spirit. As Tanya Khodkevich wrote:
You can pray freely
But just so God alone can hear.
(She received a ten-year sentence for these verses.) A person convinced that he possessed spiritual truth was required to conceal it from his own children! In the twenties the religious education of children was classified as a political crime under Article 58-10 of the Code--in other words, counterrevolutionary propaganda! True, one was permitted to renounce one's religion at one's trial: it didn't often happen but it nonetheless did happen that the father would renounce his religion and remain at home to raise the children while the mother went to the Solovetsky Islands. (Throughout all those years women manifested great firmness in their faith.) All persons convicted of religious activity received 'tenners,' the longest term then given.
(In those years, particularly in 1927, in purging the big cities for the pure society that was coming into being, they sent prostitutes to the Solovetsky Islands along with the 'nuns.' Those lovers of a sinful earthly life were given three-year sentences under a more lenient article of the Code. The conditions in prisoner transports, in transit prisons, and on the Solovetsky Islands were not of a sort to hinder them from plying their merry trade among the administrators and the convoy guards. And three years later they would return with laden suitcases to the places they had come from. Religious prisoners, however, were prohibited from ever returning to their children and their home areas.) "
