The Reformation, the Jesuits and Keeping the Motto of Ad Maiorem Dei Gloriam

While I'd consider my Christian growth after I renounced Roman Catholicism to accepting Jesus Christ as my Lord and Savior to be a jump from Independent Baptist to Reformed Baptist, from non-Calvinist to Calvinist in terms of practice, I would actually think about how the Reformation greatly differed from each other.  One truly worked for the greater glory of God, the other only worked for the greater glory of the Jesuits.

Submission to authority

Luther said, "Unless I am convinced by Scripture and plain reason, my conscience is captive to the Word of God. I cannot and I will not recant anything, for to go against conscience would be neither right nor safe. God help me. Here I stand, I can do no other."

Loyola said, "Let us be convinced that all is well and right when the superior commands it," wrote Loyola. And again: "Even if God gave you an animal without sense as a master, you will not hesitate to obey him, as master and guide, because God ordained it to be so." and "All judgment laid aside, we ought to have our mind ready and prompt to obey, in all, the true Spouse of Christ our Lord, which is our holy Mother the Church Hierarchical."

Faith

Luther taught the Biblical stance of faith.  He taught the Biblical stand that faith comes by hearing and hearing by the Word of God.  

Loyola on the other hand said, "...the exterior penances are done chiefly for three ends: First, as satisfaction for the sins committed; Second, to conquer oneself— that is, to make sensuality obey reason and all inferior parts be more subject to the superior; Third, to seek and find some grace or gift which the person wants and desires."

Guilt and Sin

Luther taught, "The true way to Christianity is this, that a man do first acknowledge himself by the law, to be a sinner and that it is impossible for him to do any good work. For the law saith thou art a corrupt tree (St. Matt. vii 17)...The first part then of Christianity is the preaching of repentance and the knowledge of ourselves, of what we are, namely sinners."

On the other hand, this was documented of Loyola:
Inigo [that is, Ignatius of Loyola], instead of feeling that his remorse was sent to drive him to the foot of the cross, persuaded himself that these inward reproaches proceeded not from God, but from the devil; and he resolved never more to think of his sins, to erase them from his memory, and bury them in eternal oblivion. Luther turned toward Christ, Loyola only fell upon himself...  
Visions came erelong to confirm Inigo in the convictions at which he had arrived...Inigo did not seek truth in the Holy Scriptures; but imagined in their place immediate communication with the world of spirits...Luther on taking his doctor’s degree had pledged his oath to Holy Scripture...Loyola at his time, bound himself to dreams and visions; and chimerical apparitions became the principle of his life and his faith.

When you look at it, Loyola was focused on for the greater glory of self and the Jesuit Order rather than God with a system of works salvation.  On the other hand, the Reformation was all about, "Sola Deo Gloria" or "Glory to God Alone" which is in harmony with the phrase, "Ad Maoirem Dei Gloriam" because when all glory is to God alone, the Christian life is indeed for the greater glory of God.
