I was Lutheran at one time and understand their Confessions.Words? Save? That's like practicing magic, isn't it, pretending that there's some magical formula of incantation to salvation? Really? I would hope that you're not rightfully representing what they believe, because that sounds so outlandish and pagan...

Martin Luther was very big on the power of the Word of God doing what it speaks. Heb 11:3, Rom 1:16.
"The word of God, wherever uttered, is powerful enough to change the hearts even of the ungodly, and these are not less unresponsive and incapable than any infant."
His whole Marburg Colloquy with Zwingli hinged on...'This is my Body', (that was Luther) unfortunately, today we add man's reasoning to God's Word.
No, I don't hold to paedo-baptism as I saw it's motive and fruit in the Lutheran Church.
