The Ukrainian Catholics continued to exist underground for decades and were the subject of vigorous attacks in the state media. The clergy gave up public exercise of their clerical duties, but secretly provided services for many lay people. Many priests took up civilian professions and celebrated the sacraments in private. The identities of former priests could have been known to the Soviet police who regularly watched them, interrogated them and put fines on them, but stopped short of arrest unless their activities went beyond a small circle of people. New secretly ordained priests were often treated more harshly.
