via Vatican News:

In 2020, the church in Italy marked the 50th anniversary of the “renewal of catechesis” following the Second Vatican Council. “The catechesis inspired by the Council,” said Pope Francis, “is continually listening to the heart of the man, always with an attentive ear, always seeking to renew itself.”

Pope Francis insisted: “This is the Magisterium. The Council is the Magisterium of the Church. Either you are with the Church and therefore you follow the Council, and if you don’t follow the Council or you interpret it in your own away, as you desire, you do not stand with the Church.” He asked that there be “no concessions to those who seek to present a catechesis that does not agree with the Magisterium of the Church.”
