That does appear to be the main claim made by advocates pf women's ordination. And why wouldn't it be, when Scripture and Tradition are solidly on the side of the opposite POV?
I don't think Scripture is of the opposite POV at all.
The world of the OT and NT appears to have been mostly male dominated - often it says "tell the men", "call the men", "the men have sinned". It lists various men, but rarely their wives, sisters or daughter. When Jesus fed a large crowd we read "the number was 5.000 men - not counting women and children". That says it all; women were 2nd, or even 3rd class citizens. The Pharisees used to daily thank God that they weren't women.
Girls were the responsibility of their husbands until they could be married off - boys could usefully go out to work and bring money in, and were the heirs. Women could be divorced on the whim of their husbands, could not be educated, were unreliable witnesses in court and could not give evidence, and no doubt much else besides. It's almost like men had a "we were created first so we're the best" type of attitude.
Yet God didn't always take any notice of what "should" happen - he called Miriam to be a prophet, Rahab to save the spies, Deborah to be judge over the whole nation, Huldah to give a prophecy which would case a mini revival. The nation was saved from destruction by Esther and David's line continued after Ruth proposed to Boaz.
When he came to live on earth, God, in Jesus, taught, healed and affirmed women. He revealed that he was the Messiah to a woman, and let her go and tell her whole town. He let a woman sit at his feet, in the place reserved for male student Rabbis. He called an unclean woman "daughter". He reminded men that his Father had made men and women in his own image and chose an "unreliable" women to be the first witness to the resurrection.
After the ascension, the early church continued to affirm women. They were with the disciples before Pentecost and hosted gatherings of believers. Priscilla taught Apollos, Lydia, it seems, was one of the founder members of the church at Philippi, a church which had deaconesses; Phoebe was a deacon, Philip's 4 daughters prophesied and Paul acknowledged that he owed much to his female co workers.
The society then may have been still largely male dominated, but Jesus showed everyone a new way - women were able to pray, talk to God and proclaim his word, just as much as men were.
Jesus told his followers to love as he loved, and his church should have been setting an example to the world over the years; showing that God loves everyone and that all our gifts are from him. Yet it seems to have stepped back into the world of the OT, insisting that there are certain things that women are not allowed to do.
From what is happening today, and has been for many years, it seems that God doesn't agree with their assessment of things.
