Pope Francis said, “one either embraces it or rejects it.” In this phrasing, embrace and reject are opposites, and between them are halfway measures, compromise, or, as Pope Francis said, “negotiating.”
St. Paul uses similarly strong language in the second reading (Philippians 2:6-11). Jesus “emptied himself, … humbled himself, becoming obedient to the point of death, even death on a cross.”
In his homily, Pope Francis reflected on that reading immediately prior to the passage in question (no negotiating, embrace or reject).
