108. Why did Jesus manifest the Kingdom by means of signs and miracles?
Jesus accompanied his words with signs and miracles to bear witness to the fact that the Kingdom is present in him, the Messiah. Although he healed some people, he did not come to abolish all evils here below but rather to free us especially from the slavery of sin. The driving out of demons proclaimed that his cross would be victorious over "the ruler of this world" (John 12:31).

109. In the Kingdom, what authority did Jesus bestow upon his Apostles?
Jesus chose the twelve, the future witnesses of his Resurrection, and made them sharers of his mission and of his authority to teach, to absolve from sins, and to build up and govern the Church. In his college, Peter received "the keys of the Kingdom" (Matthew 16:19) and assumed the first place with the mission to keep the faith in its integrity and to strengthen his brothers.
