For the glory of God alone (Soli Deo Gloria)
At the end of the day, who gets the glory for salvation? Who gets the glory for the work of God and the church in this world? The Reformers proclaimed that only God gets the glory, all of it. Since salvation is by grace alone through faith alone, in Christ alone, there is absolutely no boasting of human effort whatsoever, whereas the rejection of these principles in the late Medieval Catholic Church allowed for some measure of boasting of human effort in salvation, and thus the glory of God is compromised. The principle of Soli Deo Gloria after all is the conclusion after the other four Solas, and concludes the polemics of the Reformers against Rome
As the conclusion of the Reformers' polemics, it must be admitted that this by itself does not express a substantial difference between the Reformers and Rome. After all, the motto of the Jesuits, an order founded in the Counter-Reformation, is "Ad maiorem Dei gloriam" or "For the greater glory of God." The late Medieval Catholic Church, and the Tridentine Roman Catholic Church that succeeded her, valued God's glory very highly. Even though from the Reformers' point of view, Roman Catholicism compromised the glory of God, from the Roman Catholic point of view, it was the other way around. Ignatius Loyola, the founder of the Jesuit order, was passionate about God, and his desire to overthrow the Reformation stemmed from his conviction that the Reformation was a sacrilege to God. His misguided zeal caused much trouble to the Reformation, but his motive was pure. Just like Saul of Tarsus before his conversion, Ignatius thought he was actually serving God in forming the Jesuit order.
What then should we learn from this Reformational principle, since passion for the glory of God is not unique to the Reformation? We ought to learn that God's glory is an objective reality independent of what we humans think, say or do. First of all, God's glory is the goal of everything, our entire existence and salvation, and we ought to live and order our lives to bring glory to God. Secondly, and most importantly, since God's glory is an objective reality, we ought to examine what we do to ensure it really is giving glory to God. Ignatius Loyola thought he was giving glory to God in his zeal on behalf of the Roman Catholic Church, but he ended up glorifying a corrupt institution and bringing disgrace to the cause of Christ. Likewise, the Anabaptists thought they were glorifying God with their re-baptisms of adults, and in their sedition against secular authorities, but they were in fact bringing disrepute to the Reformation which they claimed to be a part of. It is not sufficient to desire to bring glory to God, but rather we ought to examine everything according to Scripture to discern if what we do does in fact line up with Scripture and is done according to faith in Christ.
For our modern times, this principle especially calls us to re-orientate our lives and our thoughts. Much of modern life is secular, which means as pertaining to this age. While we continue to function in this life, in study, work and society, our orientation in life should be one geared towards honoring and glorifying the God who made us and saved us from our sins. We live in this age, but we are citizens of another, the age to come. Therefore, even while it is normal to be concerned about the things of this world, we must remember that all of these, though important, is temporary. We are pilgrims in a foreign land, awaiting another.
What does this mean for believers practically? It means that believers ought to orientate their lives in the way God has commanded us. That implies paying heed to God's pattern of time in honoring the Sabbath for example, which is the fourth commandment. God has called believers to remember and honor the Sabbath, and one way of showing we actually desire to glorify God is to keep the Sabbath holy. We are to faithfully attend to what the Reformers call the means of grace: preaching, sacraments and prayer (Westminster Shorter Catechism Q88), for doing so shows our obedience to what God has commanded and provided for us. We are not to think ourselves more spiritual than God, like the mystical Anabaptists, but rather obey God in the ordinary means of grace. How can we say we want to glorify God while disobeying His direct command to honor the Sabbath?
It is of course true that the means of grace are not only all God has commanded us to do. Thus, we should seek also to be godly and grow in obedience to God in all things, in order to glorify God. Yet, here I focus upon the means of grace only because this is the more pertinent topic for us today in a culture of Evangelicalism. It is surely illustrative that for many, desire for godliness is purely a matter of internal piety, while the highly visible and ecclesiastical practices of piety are ignored or dismissed as irrelevant. But if one truly desires to grow in godliness and holiness, the first step should be the external practices of piety. It might sound easy to do, and perhaps for some it truly is easy to do, but it may not be as easy for some as for others.
In conclusion, we ought to live our lives for the glory of God alone. All of the other Solas have that as its goal, for we believe what we believe and do what we do only because we are passionate for God and His glory. Let us therefore, in view of God's grace and mercy to us, live our lives in such a manner as to glorify Him, as we learn from and extol the biblical truths taught in the other 4 Solas of the Reformation. Amen.
