Church Body, Mk 9:40, and Proetstants

[DadDave]

I’ve been reading about the orthodox/byzantine idea of an organic church as Christ’s Body (with Christ as the head of church/body). As I understand it this drives the eastern spirituality that priest without a congregation cannot have DL (as opposed to RC priests that can have them in private). This also recognized that a member’s sins not only affects others on a materially level but also affects the church body in an “unseen” spiritual way.
In light of this organic body how does this apply to Jesus’s words in Luke 9:50/Mark 9:40 “whoever is not against us is with us” and our Protestant brothers? It seems to me that in some respects (some)Protestants EC & Orthodox (and RC?) are all part of the same body. Perhaps they are like the left hand of a right-handed person – it’s not as strong and not as controlled. There may be some Protestant sects that are more like a paralyzed arm that has blood pumping through it but no feeling or use. No disparagement meant here.
Can someone flesh this out a little for me?

Any"body" who has been baptized is part of the Church Body.

They may not be in their proper relation to the earthly head, who is the Pope, yet, just like your fingers or toes when numb with cold, or your arm that numbs when caught under your sleeping body; they remain part of the Body.

There is the visible church (Catholic) in full communion, the particular Churches (Apostolic non-Catholic), and the ecclesial communities (from the reformation). Christ works though them all, but not fully.

From Dominus Iesus, 2000:

vatican.va/roman_curia/congregations/cfaith/documents/rc_con_cfaith_doc_20000806_dominus-iesus_en.htmlWith the expression subsistit in, the Second Vatican Council sought to harmonize two doctrinal statements: on the one hand, that the Church of Christ, despite the divisions which exist among Christians, continues to exist fully only in the Catholic Church, and on the other hand, that outside of her structure, many elements can be found of sanctification and truth, [55] that is, in those Churches and ecclesial communities which are not yet in full communion with the Catholic Church. [56] But with respect to these, it needs to be stated that they derive their efficacy from the very fullness of grace and truth entrusted to the Catholic Church. [57]
There is much to discuss in this, from Cardinal Kasper, 2004:
