Okay -- I finally had a chance to look this over and this was my result for holy power (not working):

lib.genHoly = function(self)
    if select(2, UnitClass("player")) ~= "PALADIN" then return end
    local ClassIcons = {}
    for i = 1, 3 do
        local Icon = CreateFrame("StatusBar", nil, ClassIcons)
        Icon:SetSize(20, 20)
        Icon:SetPoint("BOTTOMLEFT", self, "TOPLEFT", 0, 7)
        Icon:SetStatusBarTexture(config.statusbar_texture)
        Icon:GetStatusBarTexture():SetHorizTile(false)
        Icon:SetBackdrop(backdrop)
        Icon:SetBackdropColor(0,0,0,1)
        if i == 1 then
            ClassIcons[i]:SetPoint("LEFT", ClassIcons)
        else
            ClassIcons[i]:SetPoint("LEFT", ClassIcons[i-1], "RIGHT", 10, 0)
        end
        ClassIcons[i] = Icon
    end
     
    ClassIcons[1]:SetStatusBarColor(0.69, 0.31, 0.31)
    ClassIcons[2]:SetStatusBarColor(0.69, 0.31, 0.31)
    ClassIcons[3]:SetStatusBarColor(0.65, 0.63, 0.35)
 
   self.ClassIcons = ClassIcons
end

I feel like it's still over complicated, but I'm not sure where to put the frame options in the example given. I must be functionally retarded. How do!?
