it's a fact that Mary assisted with the redemptive act

Now see, right there you cross over the line. Christ's redemption of His flock is singularly His work alone.

[Terabitten]

it's a fact that Mary assisted with the redemptive act, although it's also a fact that she in no way had the power to make it more perfect;

I'm sorry, Dangus, my friend, but you can't have it both ways.

You say she assisted in the redemptive act, but had no power to make it more perfect. If she had no power to make it more perfect, then she didn't assist in the redemptive act, she merely attended. To "assist" means to help. Did Mary help Jesus in the redemptive act or not?

Asked from the other direction: Would the redemptive act have lost any of its perfection without Mary's "assistance?" If your answer is no, then Mary didn't assist, and thus should be assigned no greater reverence than anyone else who was there. If your answer is yes, that Jesus needed his mommy to help, then He isn't much of a Savior, is He?
