Authorities can also target churches. Because churches require registration to be legal, the government can deny the registration or ignore the application of some religious groups, forcing these churches to operate illegally. This gives the government an excuse to shut them down whenever they please. In these cases, the government imposes penalties on churches, including fines, the demolition of buildings, church closure, and the confiscation of property.
Churches permitted to register with the government do so under extreme scrutiny and monitoring. All churches are monitored in Cuba and may be infiltrated by citizens sympathetic to the regime and/or State security agents. Registered or unregistered, churches continue to be open for worship throughout Cuba but only as long as the government allows it. As soon as a Christian is deemed to be anti-government or anti-revolutionary, the response is swift and harsh.
