“I regard anyone who asserts the ‘sinlessness’ of Mary as a fool.”
People 2,000 years ago thought St. Paul was a fool for believing in the resurrection.
“I firmly believe there is only one who is sinless: Jesus.”
I understand.
“There is only one name by which we are saved: Jesus.”
We agree.
“There is no ‘sharing’ in that redemptive work itself, though there is sharing in Righteousness (Namely Jesus shares his with us).”
Actually all Christians communicate the message of redemption when they teach, preach or live out the gospel. We do not share in the redemptive act itself. Christ did that work. We do, however, share in teaching about the redemption and in living it out in our Christian lives.
“In as far as redemption is concerned I reject that any human helped therein, otherwise it would be quite valid to assert that Pilate is a co-redeemer with Christ for it was by his authority that Christ was put to death (though even there, that authority came from God).”
And again, it seems clear you do not know what co-redemptorix means. To disagree with it is not a problem. To disagree with something that no one actually believes in or teaches while suggesting that it is what people believe in or teach is just ignorant.
To say that ‘redemptrix’ has nothing to do with ‘redeem’ is as absurd as saying that ‘dominatrix’ has nothing to do with ‘domination.’
