Evangelii Gaudium §233

233. Realities are greater than ideas. This principle has to do with incarnation of the word and its being put into practice: “By this you know the Spirit of God: every spirit that confesses that Jesus Christ is come in the flesh is from God” (1 Jn 4:2). The principle of reality, of a word already made flesh and constantly striving to take flesh anew, is essential to evangelization. It helps us to see that the Church’s history is a history of salvation, to be mindful of those saints who inculturated the Gospel in the life of our peoples and to reap the fruits of the Church’s rich bimillennial tradition, without pretending to come up with a system of thought detached from this treasury, as if we wanted to reinvent the Gospel. At the same time, this principle impels us to put the word into practice, to perform works of justice and charity which make that word fruitful. Not to put the word into practice, not to make it reality, is to build on sand, to remain in the realm of pure ideas and to end up in a lifeless and unfruitful self-centredness and gnosticism.
