The documents issued by Pope Francis in these ten years of Pontificate are permeated by Sacred Scripture. Francis not only reaffirms that Theology “must be rooted and founded in Sacred Scripture and living Tradition” (Veritatis Gaudium, 4), but he himself puts this principle into practice, offering unique biblical reflections, direct quotations and allusions to the sacred text that make their documents look like a meditation on the scriptural text itself, with a view to illuminating current questions that must be answered by the Church. This article intends to analyze some biblical images that Pope Francis uses to talk about the Church. To achieve this objective, we first briefly reflect on the use of Sacred Scripture in its Magisterium. Next, three biblical images applied to the Church in its documents are presented: Church as “People of God”, “Body of Christ/Temple of the Spirit” and “Open House of the Father”. Finally, in the third part of the article, some biblical figures are listed, which are presented by Pope Francis as models for the Church, culminating in Mary, the “Virgin made Church” (Saint Francis). The method used is that of bibliographical analysis, considering particularly, although not exclusively, the main texts of his Magisterium, that is, hisEncyclicals, Exhortations, Letters and Apostolic Constitutions. It is concluded that the biblical data appears in Francisco’s theological work both as an argument and as a scriptural foundation for his statements and that the biblical images used by him to talk about the Church are in close consonance with his conception of a Church in dialogue and synodal.
