HEADSHIP VS ORDINATION
in my observation, "headship" has more holes than just plain "ordination". because:
1) when the husband has died, the "head" of the family is the widow.
2) when the husband is drunk, the "head" of negotiation with david and his men is the wife.
3) and also a woman pastor of literal sheep is possible, but she cannot remove the cover of the well herself
however, if one uses "headship" argument, then the context actually comes since the garden of eden because 1 tim 2:9-15 says because "the woman was deceived in transgression".
"ordination" case is simpler. just make sure it is not mixed or equivalented to "headship", "teachership", prophesying, authority and other overlapping terms. if we can isolate ordination from those terms, and focus on finding ordained women in the bible, then it seems to be clear square reasoning to do so ACCORDING to biblical ordination.
doug batchelor and others, use "headship" argument, and due to the multitude of evidence presented, it works for many. but the counter evidence will always give the opposing side some ground.
clinton wahlen uses the isolated ordination reasoning w/c in my observation is more simple, more stable, AFAIK no counter-evidence but depends on the readers'/listeners' ability to logically distinguish the non-perfect-equivalence of ordination to teaching, prophesying, having authority, etc...
