1 Corinthians 3:16

3:16 Do you not know that you are God’s temple ¹  and that God’s Spirit lives in you?

1 Corinthians 7:13

7:13 And if a woman has a husband who is not a believer and he is happy to live with her, she should not divorce him.

1 Corinthians 7:12

7:12 To the rest I say – I, not the Lord ²  – if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her.

[3:16]  ¹ sn You are God’s temple refers here to the church, since the pronoun you is plural in the Greek text. (In 6:19 the same imagery is used in a different context to refer to the individual believer.)

[7:12]  ² sn I, not the Lord. Here and in v. 10 Paul distinguishes between his own apostolic instruction and Jesus’ teaching during his earthly ministry. In vv. 12-16, Paul deals with a situation about which the Lord gave no instruction in his earthly ministry.
