Paul gives advice for Christian Unity

I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called,

1) With all lowliness and meekness,

2) with longsuffering,

3) forbearing one another in love;

4) Endeavouring to keep the unity of the Spirit in the bond of peace.

There is one body, and one Spirit, even as ye are called in one hope of your calling;

5) One Lord,

6) one faith,

7) one baptism,

One God and Father of all, who is above all, and through all, and in you all. Ephesians 4:1-6

And let us consider how we may spur one another on toward love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another–and all the more as you see the Day approaching. Hebrews 10:24,25 NIV
