In this paper, we reflect on how criticizing the Roman pontiff, Pope Francis, represents a difficulty in evangelization. Here we have emphasized the criticism directed at Pope Francis from the Catholic point of view, by clerics and laity. For this work, we mostly used internet articles on various portals where Catholic theologians write and where they question the pontificate of Pope Francis. The goal of the work as such is to show that criticism of Pope Francis makes evangelization difficult because it creates divisions within the Church. Criticisms addressed to Pope Francis reveal childish faith, but also theological rigidity. We divided the work into three parts. In the first one, we pointed out how Pope Francis is criticized and we showed that it is not constructive criticism but ad hominem criticism. In the second part, we present the teaching of the Catholic Church on the Roman pontiff. We especially emphasized the importance of the papacy as a visible unity of the faithful, which cannot be achieved by constant and imprudent criticism. In the third part of the paper, we tried to show that there is an internal conflict among the critics of Pope Francis because what they defend with all their power (tradition), they criticize the most because the papacy itself represents the teaching of the church. At the end of the paper, there is a conclusion and a bibliography.
