It would be impossible to take that class, because they are unsuitable to the job. It would be like saying that because women cannot be Navy SEALs they cannot participate in Navy SEAL training, to which not all soldiers are admitted. Even in Navy SEAL training, about 95% of those training drop out, and they are the best 5% of the army. The priesthood is similar to the army in that sacrifices have to be made and that the service is difficult. Why would someone train for a job that they are forbidden from attaining. I might want to play hockey or take nuclear physics, and no one can forbid me, but with the priesthood, the nature of the job is such that women cannot perform it effectively. Priests would kill animals in sacrifices, at least in the past. Since a woman gives life, it would be inappropriate and an aberration of her role to take life away, even if the taking away of life is only symbolical. Now, Christ Himself is the one being slain and rising from the dead. If women cannot be admitted to the priesthood, why admit them to a stage that is a stepping stone to the priesthood. Even though not all men who become acolytes will advance further, acolytes are the pool of selection for future minor and major order clerics. The rector will usually write recommendation letters to seminaries for acolytes who could be ordained. Why then admit women as acolytes if they can never be ordained. Even the deaconess was not a liturgical role in the way that the male deacon was and is; there were no liturgical actions specifically within the purview of the deaconess.
