1 Corinthians 1:23; 1 Corinthians 1:2

23 So when we preach that Christ was crucified, the Jews are offended, and the Gentiles say it's all nonsense.
2 We are writing to the church of God in Corinth, you who have been called by God to be his own holy people. He made you holy by means of Christ Jesus, just as he did all Christians everywhere -- whoever calls upon the name of Jesus Christ, our Lord and theirs.
