August 20, 2017 Twentieth Sunday in Ordinary Time Reading 1 Is 56:1, 6-7Thus says the LORD:Observe what is right, do what is just;for my salvation is about to come,my justice, about to be revealed. The foreigners who join themselves to the LORD,ministering to him,loving the name of the LORD,and becoming his servantsall who keep the sabbath free from profanationand hold to my covenant,them I will bring to my holy mountainand make joyful in my house of prayer;their burnt offerings and sacrificeswill be acceptable on my altar,for my house shall be calleda house of prayer for all peoples.
