I  thought the concept of a woman apostle was not something you would embrace. It si relevant because I see it comparable to the events at the Last Supper.  
I fail to see where the Church can find an ordination occurring at the Last Supper. I believe the supper included more than the twelve and women were present. It was an occasion that featured many symbols. The washing of feet as a model of service. The bread and wine as symbols of remembrance and continuity of presence. Turning over his mission to his disciples. It is this mission that was given to the woman at the well. If you see this as ordination then the woman at the well and the women at the Last Supper were also ordained.
