My goodness! How much wishful thinking can be packed into such a short paragraph!
First let me clear something up:
Catholics are bound by the Magisterium in their interpretation of Scripture - declaring permanently and irrevocably those issues which are closed to discussion.
Protestants, OTOH are bound by the shifting sand of their own interpretations or those of their current pastor, or favorite author. It always sounds great to say “I stand by SS as the authoritative truth” when, in fact, such truth is transitory because although it is BASED on Scripture it is PRODUCED and FORMED by the intellect; and intellects vary from person to person and from generation to generation.
Contraception is a perfect example of this. You claim to be be “bound by the Word of God” - OK, I accept you at your word. The question is, then,** are you bound by the Pre-1930 word of God which unanimously rejected contraception** or by the word of God of today or the word of God of tomorrow which embraces it non-chalantly???
It’s an important question because every single one of those who founded the Reformation that you gloriously recognize were “bound by the Word of God” and that binding included the Word of God telling them that contraception was a grave sin.
**So the question remains, which Word of God are you bound to? ** **The Word which revealed the sinfulness of contraception to them, or the same word which justifies it to you? ** The Word of yesterday, today or tomorrow? Those are the facts as revealed by the 500 years since the glorious Reformation that you speak of: The truth of Scripture, alone, speaks different Truth to different generations.
Blessings!
