"There are only two sorts of people in life you can trust - good Christians and good Communists"

This quote by Joe Slovo recommends that there are just two kinds of people in life that can be relied on: excellent Christians and great Communists. This indicates that those who are excellent Christians and excellent Communists are trustworthy, while those who are not might not be. Slovo's quote recommends that the 2 groups have something in typical that makes them trustworthy, although it is not defined what that is. It could be that both groups have a strong moral code and a dedication to their beliefs that makes them dependable. Additionally, it might be that both groups have a shared understanding of the importance of loyalty and sincerity. Whatever the reason, Slovo's quote indicates that these 2 groups are the only ones that can be trusted.
