The people in the Gospel are real people, but they also represent us. Jesus’ mother and brothers and sisters represent righteous souls. His betrayer and enemies and executioners representful wicked souls. That is why those who do God’s Will are really His mother and brothers and sisters and why those who sin crucify Jesus anew.
But who dose Jesus represent? For He is also a Person of the Gospel! Jesus represents the Catholic Church. The Church is His Body. The Church continues Jesus’ mission of delivering souls from evil by her prayer, her sacraments, her teachings, her rites, and such things. She is the Sacrament of Salvation.
