Word on Fire: International Q&A w/ Bishop Barron

In today’s episode, Bishop Barron fields questions from people all over the world, including:

How do we reconcile love as willing the good of the other with more exclusive love, such as the love between a husband and wife?
Some Protestant theologians say that John 6 is not talking about transubstantiation because this dialogue took place before the institution of the Eucharist. What do you think?
What does the Catholic Church say about predestination and free will?
Why does God need to be worshiped and glorified, and need sacrifices? On human terms, this sounds like his love is conditional and he is insecure.
Can dogma be changed or overthrown?
Was Jesus a socialist?
What are the essential qualities/qualifications needed for evangelism? Degrees or degree program recommendations?
