From: LUMEN FIDEI, First Encyclical of Pope Francis
39. It is impossible to believe on our own. Faith is not simply an individual decision which takes place in the depths of the believer’s heart, nor a completely private relationship between the "I" of the believer and the divine "Thou", between an autonomous subject and God. By its very nature, faith is open to the "We" of the Church; it always takes place within her communion. We are reminded of this by the dialogical format of the creed used in the baptismal liturgy. Our belief is expressed in response to an invitation, to a word which must be heard and which is not my own; it exists as part of a dialogue and cannot be merely a profession originating in an individual.
