On Friday a historic meeting took place in Havana, Cuba. Vatican TV covered it HERE … Advance to 8 minutes to see signing and their remarks.
A discussion of its significance was attempted HERE.
Having just finished reading numerous volumes comparing Roman Catholic, Eastern Orthodox and Protestant (Evangelical and Reformed) theologies, we need not expect much more than what has just happened. There are significant differences between them and those differences will likely not be bridged this side of Heaven. Cooperation is possible, friendship is happening, but unity in faith and practice is unlikely.
