5 Solas

Was the Reformation necessary? I believe it was not only necessary but that it isn't over. "Semper Reformenda" (always reforming)is still the cry of the thoughtful.
The Reformation acknowledged our dependence on grace and not merited favor, sola gratia (grace alone). "...being justified freely by His grace..." Rom 3:23
We realized that the instrument of saving grace was "sola fide" (faith alone) and not the working of any sacraments or any other experience or rite or ritual. "...a man is justified by faith and not the deeds of the law." Rom 3:28
The reformers understood the "...Holy Scriptures lead you to salvation..." 2 Tim 3:15 and are the only sufficient authority for faith and obedience. The church is an ordained support to that truth but not another authority in and of itself. They said "sola Scriptura" (Scripture alone).
The central Person of all the Bible is Jesus the Christ who accomplished redemption for all who believe. "...the redemption that is in Christ Jesus..." Rom. 3:24. So our faith is in a Person Who is God, "solo Christo" (Christ alone) and not another such as Mary or any organization etc.
"I am the LORD, that is My name; And My glory I will not give to another..." Is. 42:8 The glory of God is central to the purpose of God and ought to be the passion for the church. "Soli Deo Gloria" (God's glory alone) is the purpose of all the above.
By grace alone, through faith alone, on the word alone, because of Christ alone, to the glory of God alone.
