1. The description of sin
1 It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife. 1 Corinthians 5:1 (ESV)
7 You shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. 8 You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. Leviticus 18:7-8 (ESV)
2. The dereliction of the Church
2 And you are arrogant! Ought you not rather to mourn? . . . 1 Corinthians 5:2 (ESV)
1 What shall we say then? Are we to continue in sin that grace may abound? 2 By no means! How can we who died to sin still live in it? Romans 6:1-2 (ESV)
6 Then Ezra withdrew from before the house of God and went to the chamber of Jehohanan the son of Eliashib, where he spent the night, neither eating bread nor drinking water, for he was mourning over the faithlessness of the exiles. Ezra 10:6 (ESV)
1 But the people of Israel broke faith in regard to the devoted things, for Achan the son of Carmi, son of Zabdi, son of Zerah, of the tribe of Judah, took some of the devoted things. And the anger of the LORD burned against the people of Israel. Joshua 7:1 (ESV)
3. The dismissal of the erring Church member
2 . . . Let him who has done this be removed from among you. 1 Corinthians 5:2 (ESV)
18 Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. Matthew 18:18 (ESV)
