I dont see this laity/clergy distinction in the body.
I see it more as a maturity level. (IMO)
Paul, the Apostle, in his letter to the Ephesians,
wrote down how the body would function.
Those who are to do the equipping,
those who are being equipped
(and who will in turn be equipping others)
But as we all know, even while WE are being
equpped, we are also involved in the equipping
of others.
He begins by reminding them of their calling:
Eph 4:
Therefore I, a prisoner for serving the Lord,
beg you to lead a life worthy of your calling,
for you have been called by God.
How?:
2 Always be humble and gentle.
Be patient with each other,
making allowance for each other’s faults because of your love.
3 Make every effort to keep yourselves united in the Spirit,
binding yourselves together with peace.
WHY?:
4For there is one body and one Spirit,
just as you have been called to one glorious hope for the future.
5 There is one Lord, one faith, one baptism,
6 and one God and Father,
who is over all and in all and living through all.
7 However, he has given each one of us a special gift
through the generosity of Christ.
8 That is why the Scriptures say,
“When he ascended to the heights,
he led a crowd of captives
and gave gifts to his people.”
9 Notice that it says “he ascended.” This clearly means that Christ also descended to our lowly world. 10 And the same one who descended is the one who ascended higher than all the heavens, so that he might fill the entire universe with himself.
11 Now these are the gifts Christ gave to the church:
the apostles,
the prophets,
the evangelists,
and the pastors and teachers.
12 Their responsibility is
to equip God’s people to do his work and build up the church, the body of Christ.
13 This will continue until we all come to such unity in our faith and
knowledge of God’s Son that we will be mature in the Lord,
measuring up to the full and complete standard of Christ.
14 Then we will no longer be immature like children.
We won’t be tossed and blown about by every wind of new teaching.
We will not be influenced when people try to trick us with lies so
clever they sound like the truth.
15Instead, we will speak the truth in love,
growing in every way more and more like Christ,
who is the head of his body, the church.
We meet at church for this 'equipping', as we are ALL
able ministers of the gospel and each member of the
body has a special purpose and role.

At my church, this is something that we learn by
'example'. The 'equippers' are bright shining examples,
causing those who see that light in them, to desire
that same level maturity in Christ as we study
and grow in truth and love.
Naturally, the only way any of this could be possible
(the shining like lights of the universe) is through
the infilling of the Holy Spirit and the trust that
comes from speaking out the truth, in love.
Sorry my post is so messy, hope it blesses you.
