In essentials ... unity
In non-essentials ... diversity
In all things, love.
Ephesians 4:2-6 (NIV)
Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit-- just as you were called to one hope when you were called-- one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all.
