Actually Benhur, to say that the Lutherans were the first “protestant” church is not totally acurate. While Luther was one the forefront of the reformation, there were already others at work . Luther, and Lutheranism benefited from many governments of the day establishing Lutheranism as the new state religion. Along with the establishment of the Church of England, these two became the primary protestant bastions , but others such as Zwinglii, Calvin , et al were searching scriptures and drawing closer to the actual biblical faith.
Luther was very instrumental, but he was not alone. I feel that the increasing access to scripture was critical to the development of breakaway churches. Sola Scriptura, Sola Fide and access to the Scriptures empowered people to learn the truth.
As to the OP, yes it does matter in as much as one must use biblical discernment to determine if the church you are attending holds to the fullness of the Gospel and the teachings from the epistles. Now before my Catholic bretheren jump on that last sentence, i said the fullness of the Bible, not the fullness of everything created and added by man on top of the Bible.
