Be watchful, stand firm in the faith, act like men, be strong. Let all that you do be done in love…If anyone has no love for the Lord, let him be accursed. Our Lord, come! (1 Corinthians 16:13-14,22 ESV)
Many study groups fast forward through the final chapters in the Apostle Paul’s letters thinking that the names listed are difficult to pronounce and the overt lesson is over. This is a mistake.
In Chapter 16 Paul deals with at least 3 very controversial issues in the church:
Mission giving and financial integrity;
Support and acceptance of church leaders; and
Boundaries on the Christian community.
Missions and Financial Integrity
The Jerusalem council imposed 4 requirements on Gentile converts: …abstain from what has been sacrificed to idols, and from blood, and from what has been strangled, and from sexual immorality (Acts15:29 ESV) . Paul mentions only one requirement: remember the poor (Galatians 2:10). By that, he particularly meant the poor saints in Jerusalem. He reasoned: For if the Gentiles have come to share in their spiritual blessings, they ought also to be of service to them in material blessings (Romans 15:27 ESV).
It is interesting that Paul, who took no support from the church in Corinth (1 Corinthians 9), was especially careful to request that they appoint their own trustees for the collection for the poor saints in Jerusalem (v 3).
In the middle of church divisions, Paul sends in a turnaround team and highlights the work of theologically sound, local leaders. In commending the household of Stephanas, he highlights their spirituality (first converts) and conduct: they have devoted themselves to the service of the saints—be subject to such as these, and to every fellow worker and laborer (vv 15-16)
Boundaries on the Church
While the church is open to everyone, the church does not consist of everyone. Paul states: If anyone has no love for the Lord, let him be accursed. Our Lord, come! (v 22)  The mark of a Christian is love for the Lord, not affiliation or family ties. Given this presupposition, Paul advises: Be watchful, stand firm in the faith, act like adults, be strong. Let all that you do be done in love (vv 13-14).
The mention of the household of Stephanas (v 15) as well as Aquila and Prisca (v 19)  underscores the importance of family ministries, especially husband-wife teams, in the early church.
 This list contains 3 food requirements and behavioral requirement. Each requirement focuses on sins of the body.
 “Our Lord come” is written in Aramic (μαράνα θά; Marantha) suggesting again that the earliest confessions included statements of Christ’s divinity and expectations of the second coming.
