Likely wrong, but my sense is that love for the vulnerable was not "the" early Jesuit passion, but rather for the Church, the "church threatened" (remember the special vow to the Pope?). Of course it evolved. 
My sense is that the Jesuit Pope saw that and maybe it was why he chose the Franciscan in his mission. It was the love of creation, the incarnate expression of God, dormant, living, suffering, singing that the new Pope saw was needed. 
He sees the differentiation of Church/creation, religious/secular, "thesis/antithesis" approaching a critical point of antipathy and the need for a integration possible only at an incremental level. It is time for the institution, like Jesus, to become incarnate and risk; for those prepared to respond.
The notion of marriage is the risk, leap of faith in other, mutually.
The metaphor: "leap" of mutuality in-
soul bearing friendship
peership
accountability
atonement and growth
discernment, nurturing, security of intimacy
