Dear brothers and sisters: In our continuing catechesis on the Ten Commandments, we now turn to the eighth commandment: “You shall not bear false witness against your neighbour”. The Catechism of the Catholic Church explains that this commandment “forbids misrepresenting the truth in our relations with others” (No. 2464). We are called to be truthful not only in our words but in our entire way of acting towards others. Our ultimate model in this regard is Jesus himself. He is the truth in person (cf. Jn 14:6), who, at his trial before Pilate, revealed that he came into this world to testify to the truth (cf. Jn 18:37). In the mystery of his life, death and resurrection, he disclosed the deepest meaning of our life on earth, and invited us to share in his divine life. His gift of the Holy Spirit, the Spirit of truth, enables us to become adoptive sons and daughters of our heavenly Father and to dwell in his love as brothers and sisters. The eighth commandment bids us live this new life to the full, and thus to bear true witness to God’s saving love, made incarnate in the humanity of Christ our Lord.
