A mother ignores her son’s slamming door, and at dinnertime, she sets his plate before him as usual. At the office, a colleague receives an award that another had earned, and the latter doesn’t protest; at home, after an argument, one of the two reaches for the other’s hand unexpectedly. These acts of forgiveness go unreported. We only hear about the visible kind: the hug, the words, the public gesture that heals a known wound. The invisible kind is the submerged part of the iceberg, much larger than the visible portion, and the part that sustains it.

The unity of a family rests on the thousands of small acts of forgiveness each day. A marriage doesn’t learn in forty years how not to hurt each other. It learns to forgive the hurt that is done, again and again, without ceremony. A friendship is sustained by the invisible concessions of each week. Between siblings, the wounds are older, an unresolved rivalry or the apparent favoritism of their parents, and forgiveness can take years to arrive. One of the great stories of the Old Testament is that of Joseph forgiving the brothers who had sold him into slavery: “You intended to harm me, but God intended it for good” (Genesis 50:20).

From the outside, those who endure with resentment and those who endure by forgiving may seem the same. The former accumulates silences that eventually fester. The latter keeps their heart free to continue loving. In that inner difference lies what I call the mystique of forgiveness: the hidden depth of the ordinary gesture, the way in which a small act, a protest left unspoken, or a body that returns to seek the other, reaches a region of the soul that the observer cannot see. The home or the office are already mystical places, even if no one calls them that.

Some people have experienced forgiveness with such intensity that their lives have become a testament to others. Edith Stein, a German Jewish philosopher and brilliant disciple of Edmund Husserl, converted to Catholicism and entered the Carmelite convent in 1933, with Nazism already in power. She took the name Teresa Benedicta of the Cross. In 1938, she was moved to the Netherlands for her protection. There, she wrote a testament in which she offered her life, among other intentions, for the salvation of Germany, the country that was going to kill her, and for world peace. On August 2, 1942, in retaliation for the pastoral letter in which the Dutch bishops protested against the deportation of Jews, the SS stormed the convent in Echt and took her away along with her sister Rosa, also a convert. “Come, we are going for our people,” she told Rosa. They died in Auschwitz on August 9.

Another woman murdered in a Nazi camp belonged to a different Christian tradition: the Orthodox. Elizaveta Pilenko was born in Riga in 1891 into a Russian aristocratic family and was a poet of some renown. In Parisian exile, she buried one of her young daughters. In 1932, she took her vows as a nun, taking the name Maria, and shortly afterward opened a shelter for impoverished émigrés at 77 rue de Lourmel. During the Nazi occupation, Maria Skobtsova turned that house into a hiding place for persecuted Jews and, together with Father Dimitri Klepinin, forged baptismal certificates that saved numerous lives. The Gestapo arrested her in February 1943. She died in the gas chamber at Ravensbrück on March 31, 1945, Holy Saturday, possibly after offering to take the place of a younger Jewish companion. The Ecumenical Patriarchate of Constantinople canonized her in 2004. Her fellow prisoners recalled that she listened to those who no longer wanted to live. For her, loving and forgiving were one and the same.

These lives are just the tip of the iceberg. Beneath it, in anonymity, are millions of people: children who call again without ever having received an apology, and neighbors who let the offense go unpunished. Without these acts of forgiveness, no family or community would remain standing. The mystique of forgiveness is not the privilege of a few. It springs forth from the hidden depths of the soul, where one can embrace God.
