35. Another painful chapter of history to which the sons and daughters of the Church must return with a spirit of repentance is that of the acquiescence given, especially in certain centuries, to intolerance and even the use of violence in the service of truth.

It is true that an accurate historical judgment cannot prescind from careful study of the cultural conditioning of the times, as a result of which many people may have held in good faith that an authentic witness to the truth could include suppressing the opinions of others or at least paying no attention to them. Many factors frequently converged to create assumptions which justified intolerance and fostered an emotional climate from which only great spirits, truly free and filled with God, were in some way able to break free. Yet the consideration of mitigating factors does not exonerate the Church from the obligation to express profound regret for the weaknesses of so many of her sons and daughters who sullied her face, preventing her from fully mirroring the image of her crucified Lord, the supreme witness of patient love and of humble meekness. From these painful moments of the past a lesson can be drawn for the future, leading all Christians to adhere fully to the sublime principle stated by the Council: "The truth cannot impose itself except by virtue of its own truth, as it wins over the mind with both gentleness and power".(19)
