Just as baptism leads to identification with Jesus’s divine Sonship, making us by adoption what belongs to Jesus by nature, so too in John this baptism-like scene provokes an understanding of our ongoing identification with and consideration of our life in Christ.
The work of preparing to receive Holy Eucharist is not meant to scare us off. Nor is it meant to erect barriers. On the contrary, our preparation is meant to instill within us reverence and respect for the incredible gift of the Eucharist.
Hospitality does not mean inviting people into the most sacramentally intimate spaces of the Christian life, it means being honest about intentions, healthy boundaries, the shape and form such commitments will take, and yes, eventually, the intimate sharing of one body with another. If consent is important in our debates about sexual boundaries, how is it also not important for sacramental boundaries?
By saying this prayer, those of us who are Gentiles become like the Syrophoenician woman. We admit we are dogs, unworthy as Gentiles and those who chronically forget God’s promises to the Jews to sit at God’s table, and yet we go on to ask for God’s food all the same, trusting that our host is merciful.
