One accord

The level of unity amongst one another in the church is to be of the highest order attainable! If this were not to be attainable, Jesus wouldn't have prayed so in the garden of Gethsemane. The early church we find, were mightily empowered by the Holy Spirit to live in such a divine unity and accord:

John17:18, As thou didst send me into the world, even so sent I them into the world.
19, And for their sakes I sanctify myself, that they themselves also may be sanctified in truth.
20, Neither for these only do I pray, but for them also that believe on me through their word;
21, that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us: that the world may believe that thou didst send me.
22, And the glory which thou hast given me I have given unto them; that they may be one, even as we are one;
23, I in them, and thou in me, that they may be perfected into one; that the world may know that thou didst send me, and lovedst them, even as thou lovedst me.

Acts 2: 1, ¶ And when the day of Pentecost was fully come, they were all with one accord in one place.
