1 Corinthians 1:9-10

9God is faithful, who has called you into fellowship with his Son, Jesus Christ our Lord.

A Church Divided Over Leaders 10I appeal to you, brothers and sisters, The Greek word for brothers and sisters (adelphoi) refers here to believers, both men and women, as part of God’s family; also in verses 11 and 26; and in 2:1; 3:1; 4:6; 6:8; 7:24, 29; 10:1; 11:33; 12:1; 14:6, 20, 26, 39; 15:1, 6, 50, 58; 16:15, 20. in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought.
