First, the word body has two main meanings. One sense is the human anatomy. This sense implies a physical self that includes bones, organs, muscles and skin as one body. This is the most commonly understood sense. The second, is a group of people or things functioning as one unit, like an advisory body, a society or an association.
The same variation in meaning applies to the word church. The original Latin word for church is ecclesia meaning a congregation or an assembly of believers. Whereas its English rendition also means; house of the Lord, a public place of worship, a building.
Pope Pius XII in his Encyclical Letter, Mystici Corporis explains that “the Church is the body of Christ”. By Church Pope Pius XII means ecclesia or the congregation of believers. Hence, the resurrected body of Christ IS the body of faithful Christians in the world.
The mysterious workings of the Risen Body of Christ can be illustrated by history whereby Christians who without a central government, no imposition of taxes and without a standing army, took over the Holy Roman Empire. Herein stands the invisible and living power of the Resurrected Body of Christ.
Harari, at best you lack the necessary spirituality to understand what the Resurrected Body of Christ IS. At worst you are a fake human being. That’s why you worship robots, you value “artificial” intelligence, and are trans-humanist rather than a humanist.
