The recent video put out by Pope Francis is a contradiction to basic Biblical doctrine, that Christ is the only way of salvation and the only way to reach God.
A Roman Catholic may say something like, "the Pope actually never directly contradicts those verses; he is just saying we should talk and dialogue with one another, with people from other religions, and we should consider all people "children of God"; and they are sincerely seeking for God and they "believe in love" also. Turretinfan is correct about the proper understanding of "Children of God" ; yet the Roman apologists would probably say that the Pope means that we are all children of God in the sense of nature and creation - "brothers and sisters in humanity". He should make that clear, if he wants to preach truth and the gospel with other people of other religions.
The failure to preach the gospel and speak the truth in this context is a failure of basic responsibilities of a pastor/elder/overseer (bishop). He (and the doctrine of the Papal office) claims to be "the bishop over all bishops", and this is a massive failure of duty.
We can still have respectful dialogue with other religions, but we need to preach the gospel (2 Timothy 4:1-7), be involved in Christian apologetics and speak it with gentleness and respect ( 1 Peter 3:15), speak the truth in love (Ephesians 4:15-16), and defend the faith once for all delivered to the saints. (Jude 3) But the Roman Church officially rejected justification by faith alone at Trent (1545-1563) and has been adding more and more traditions of man (Mark 7; Matthew 15; Colossians 2:8) to their dogmas.
The video gives the impression that Buddhism, Judaism, and Islam are equally valid roads to God and understanding of what true love is. The plastic baby doll Jesus as representing Christianity is typical Roman Catholic external physical emphasis that is crude and gaudy and comes across, when RCs stand before it and pray and worship, - it comes across as idolatry. As does praying to Mary.
If post Vatican 2 theology is wrong (and it certainly seems to contradict previous RC theology, especially in the official Catechism of the Catholic Church, # 841 (Muslims worship the same God as Christians) and 847 (atheists and pagans who have never heard of Christ can be saved), then this is another step in showing why there are the "Traditional" Roman Catholics, the "Rad-Trad" Roman Catholics and Sedevacantists, and the whole RC claim of unity is an empty promise. And it also shows that Papal infallibility is wrong.
As John Bugay has commented on this video also, the Pope is channeling the classic liberalism of "Adolph Von Harnack"
