While I do not assume your interpretations of those things are accurate, even if I did, it would still be true that all those things are equally consistent with a sinner saved by grace. For with God, all things are possible, are they not?
we also know the nature of grace as antidote of sin
But grace has provided all of us who believe with the antidote for sin in the blood of Christ shed for our sins. So grace not only doesn't prove sinlesness, it strongly infers a prior state of sin for which the grace was needed as antidote. Even Mary in her wonderful hymn of praise to God recognizes Him as her Savior, and who needs a savior but one who needs to be saved? Which she here freely admits she does.
Right. A sinner can be filled with grace along the pattern of Mary, and expel the sin from inside of himself with Christ's help and become like Mary, free from sin. We pray "Lord, forgive me my sins and with Thy help I shall not sin again".

No, not "infers", any more that the Sun shining on Earth does not strongly infer that the Earth is covered with ice. Indeed Mary herself cites God as her "Savior" (in the Magnificat) but that does not infer that she had sinned, simply that she is free from sin, -- saved, -- from conception.
Dear everyone,
That is all I have time for today, I will answer the rest when I find time. Have a blessed weekend and come, celebrate the Palm Sunday with us.
