Why you should hug at the Sign of Peace

Why you should hug at the Sign of Peace August 19, 2018

This summer, I’ve been going to daily Mass at a parish down the street from my internship, where the youngest folks in attendance are baby boomers. Once the little old ladies got over their shock (“a YOUNG person! at DAILY MASS!!”) they began welcoming me with open arms – literally. During the Sign of Peace, a few walk over to my pew and embrace me with sincere affection. I’m not weirded out by this, because at Notre Dame it’s standard protocol to hug everyone within a 10-foot radius. It’s pretty aggressive.

Some days, though, I long to sit far away out of arms’ reach of these lovely grandmothers. When I am deep in prayer throughout the Liturgy of the Eucharist, human contact can feel like an intrusion, and I’d rather remain in unbroken spiritual profundity. When I experience moments of intimacy with God, I am frequently tempted to turn inwards and shut out the world.

But the Christian cannot retreat into individual experiences of the transcendent at the expense of communion with others. That’s antithetical to the Eucharist, which unites all the faithful to Christ as we become the Body of our Lord – the Church.  As Giussani writes, our duty is to bring about communion in the world: “This is the law of the Christian, nothing more.”

So why is the Sign of Peace – the handshake, hug, or kiss before the Eucharist — so important? This moment of physical touch isn’t just a symbol or reminder of what the Eucharist accomplishes. It actually aligns our biological reality with the truth of the Eucharist.

The neurobiology of the Sign of Peace

Oxytocin is a peptide hormone frequently called the “love hormone.” Although its effects on the body are complex and should not be reduced to this simplistic moniker, oxytocin certainly can promote love. High levels of oxytocin reduce stress, improve social cohesion, and increase compassion. More particularly, oxytocin release facilitates nurturing interactions between mothers and their infants. Finally, it is essential to the formation of pair bonds, or monogamous relationships.

Interpersonal touch is one of the surest ways to increase your level of this hormone. Gestures like handshakes and hugs, particularly when accompanied by a smile and eye contact, boost oxytocin and decrease cortisol.

Christ Himself knew the power of physical touch: He embraced children and kissed lepers. His touch brought reconciliation and healing, particularly to those on the margins of society. St. Paul asks us to carry this forward, to “greet all the brothers and sisters with a holy kiss” (1 Thessalonians 5:26.) The Sign of Peace at Mass is the modern image of that ancient practice.

So the Sign of Peace, through oxytocin, promotes biological unity among the faithful. It actually conforms your brain and body to the truth of the unity accomplished by the Eucharist.

Why is this so important?

Because, as Giussani explains, “It is not our experiences that build unity, but rather unity that is the foundation for our experiences.” Unity in the Body of Christ is not the consequence of your relationship with God. We do not build up His Church by our personal piety or our efforts at holiness. No, the unity of the Church was achieved by the death and resurrection of Christ. Christ invited us into unity when “in one Spirit we were all baptized into one body” (1 Corinthians 12:13). And now, this unity becomes the starting point for our experience of God.

The temptation to retreat into isolated experiences of the transcendent can be strong – especially if you have a mystical heart like mine. But we cannot overlook the importance of communion.

As Giussani writes:

“We are together because Christ died and rose again,” so “all your objections to those who don’t do anything, or who always want to be in charge, or who do as they please, or who you don’t get along with, or who leave you alone; all your objections, which are the reason you stay at the edges or the margins of the life of the community— where do they come from? From the fact that, for you, it’s not yet true that we’re together because Christ died and rose again. Because even if you killed my mother I would have to accept you in communion; even if you killed me I would have to accept you in communion— because even if you killed me, you cannot get rid of the fact that Christ died and rose again for our unity.”

So don’t give in to the temptation to retreat from community, and get stuck in your own head. When you’re at Mass, give the Sign of Peace! Your neurobiology will help you live according to the truth of our unity in Christ: oxytocin will make you more ready to receive the Eucharist of your Lord.
