“Do not bear false witness against your neighbour” (Ex 20:16) is the 8th commandment. The New Testament tells us, unmistakeably: “But let your statement be ‘Yes, yes’ or ‘No, no’; anything beyond these is of evil.” (Mt 5:37). Without a doubt: God wants us to be truthful in what we say and do! What does this mean for politics? In a democracy, voters expect, on the one hand, that politicians tell the truth; on the other hand, politicians often weigh up whether a gentler handling of the “absolute truth” would be more humane. The desire for truth poses great challenges for both politicians and voters!
