This is well said by Francis. The full implication is of great importance. While, "We do not need to be afraid of questions and doubts because they are the beginning of a path of knowledge and going deeper," and, "One who does not ask questions cannot progress either in knowledge or in faith," the process of trying to make maximum sense of spiritual things is necessarily a personal process, for making sense involves fitting the spiritual things into our matrix of experience and understanding, welding it to what is known and sensed uniquely in each person. It is a constructivist process. We should expect that, as people go deeper and progress on the path of knowledge, there may be more divergence in insights and ideas than institutional religion feels comfortable with. Francis seems far less afraid of this than most in the upper echelons of the Church.
