I believe they sincerely want to make this movie attractive to the faithful Christians, but there are so many serious flaws in the movie. The Church does not easily approve miracles like that. And for a person to be approved as a saint, it takes years AFTER a person die to investigate and then determine if he or she is worthy to be venerated as a saint. I have never seen the congregation waiting for another priest to give homily, especially when he is not there from the beginning of the Mass. The words of God and the homily is a serious matter and a priest who gives the homily is always taken his responsibility very seriously. Besides, there are two major flaws in this movie: 1) The Catholics do not practice their faith in the confessional room as it is described here; 2) Jesus Christ comes back the second time not as a carpenter.
1) First, the confessional room is a sacred place, not a chatting room. Second, only a penitent and a priest allow to be in the room. No third person allowed to stick his head into the room like that in the movie. Anything said in the confessional room is secret and the priest cannot break the seal of confession. Not a single word in a confessional room is allowed to be discussed outside. Any priest who breaks the seal of confession is subject to the church's most severe penalty — automatic excommunication, revocable only by the Pope.
2) It is true that the Church is waiting for Jesus to come back the second time but she expects Him to come in glory to judge all nations. This is how the Bible said the second coming of Jesus: “When the Son of Man comes in his glory, and all the angels with him, he will sit upon his glorious throne, and all the nations will be assembled before him. And he will separate them one from another, ...Then the king will say to those on his right, ‘Come, you who are blessed by my Father. Inherit the kingdom prepared for you from the foundation of the world. For I was hungry and you gave me food, I was thirsty and you gave me drink, a stranger and you welcomed me, naked and you clothed me, ill and you cared for me, in prison and you visited me ...Amen, I say to you, whatever you did for one of these least brothers of mine, you did for me.’ Then he will say to those on his left, ‘Depart from me, you accursed, into the eternal fire prepared for the devil and his angels ... what you did not do for one of these least ones, you did not do for me.’ And these will go off to eternal punishment, but the righteous to eternal life.” (Matthew 25: 31-46). The bible also said, “Men of Galilee, why are you standing there looking at the sky? This Jesus who has been taken up from you into heaven will return in the same way as you have seen him going into heaven.” (ACT 1:11)
