Jesus prayer that they all be one.

Jesus did not have any delusion that the world would believe. Jesus made it clear that most in the world would not believe. The prayer was for believers not unbelievers.

Jesus prayer was fulfilled at Pentecost when all who became members of the the Body of Christ became one Body.

If anyone does not believe the only way that God provided to enter His Body there in nothing to unify on. Also, just because true believers have unity in the body of Christ in the Spirit does not mean that we will see things the same way while living in the flesh on earth.

clipped from www.catholicnewsagency.com He continued, “When at the last supper, Jesus prayed that “they all might be one”, he had in mind the precise end, “that the world believe.” The evangelical mission of the Church is thus an ecumenical walk, a journey of unity in faith, in evangelical witness and authentic fraternity.”
