1. Since the church is the dwelling place of God's Spirit, the people who make up the church should work for unity by building each other up.	1:10–4:21 (esp. 3:10–16; 14:12)
2. Christians should build up the church in four practical ways:
a. they should be sensitive to those of fragile faith.	8:1–9:18; 10:28, 33
b. they should win unbelievers through culturally sensitive evangelism.	9:19–23; 10:27, 32–33
c. they should conduct worship services in such a way that unbelievers present might come to faith.	14:16, 23–25
d. their corporate worship should use spiritual gifts not for personal display, or evaluating who has a better gift, but to build up the church.	11:2–16; 12:12–30; 14:1–35
3. Sexual relations form a union between man and woman as profound as the union of the believer with Christ, and so sexual activity should be confined to marriage.	5:1–13; 6:12–20; 7:5, 9, 36
4. Baptism and the Lord's Supper are important, but both are subordinate to personal trust in the gospel and to living in the way that God commands.	1:14–17; 10:1–5; 11:17–34; 15:29–34
5. The bodily resurrection of Jesus (and of his followers) from the dead is a critical component of Christian faith and practice.	6:14; 15:1–58
