The Hebrew term for peace is shalom, which is related to the word shleimut, meaning full or whole.
Shalom requires radical inclusion — we can’t be whole unless everybody is included — and harmony — it can’t be peaceful unless all the diverse peoples commit to getting along with one another.
Peace is possible only when diverse peoples feel a deep connection to, and responsibility for, each other, and when people of every belief and background embrace each other as siblings.
