Exodus 6:27 (Darby) These are they who spoke to Pharaoh king of Egypt, to bring out the children of Israel from Egypt: this is that Moses and Aaron.

Not every translation translates the above verse as above. However, the specific grammar of this translation brings out an important point.

Normally,  in English grammar, when dealing with two or more individuals, the verb would be plural “are”.  If that were the case here, then it would read…these are that Moses and Aaron.

But the verb is singular, “is”.

Moses and Aaron worked as one unit, like two poles of a battery.

The same principle is again seen as Jesus sent his disciples out two by two.

Mark 6:7 And he called unto him the twelve, and began to send them forth by two and two; and gave them power over unclean spirits;

Luke 10:1 After these things the Lord appointed other seventy also, and sent them two and two before his face into every city and place, whither he himself would come.

2 Therefore said he unto them, The harvest truly is great, but the labourers are few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.

The Church, larger than individual denominations, to be successful, must work together.

Jesus praying, recorded in John 17, prayed this:

John 17:20 Neither pray I for these alone, but for them also which shall believe on me through their word;

21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.

22 And the glory which thou gavest me I have given them; that they may be one, even as we are one:

23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.

Individual churches may have slightly different focuses, slightly different orders of worship, and certain differences between them, just like different members of the body of Christ may have different tasks and calls.

But oneness is what brings the power of God.

The human body does not, or rather, should not fight amongst itself.  If it does, that is called an auto-immune disease and that can be very destructive.

If each part of the body of Christ focuses on the individual tasks given by God, then in unity it will become as These are they who spoke to Pharaoh king of Egypt, to bring out the children of Israel from Egypt: this is that Moses and Aaron.
