This is an old Thread, but is appropriate to my current life situation now in sorting out my own search for answers about denominational disunity.
We create a difficulty here in trying to explain Eastern Doctrine in a Lutheran context, or Calvinism in an Orthodox context, etc. We must explain a given Doctrine in context of that doctrine to see where it leads. We gain a better understanding of what that Doctrine really teaches, and a clearer understanding of the differences of where they lead.
Having said that, there are several Lutheran positions that are most often misunderstood.
Man’s freedom of will. In Lutheran context man has freedom of will, but in our sinful condition our choices to do good are based on selfish reasons, not godly reasons. In this, humans always choose sinfully, even though the work may outwardly appear good. Herein the Work of the Holy Spirit is paramount in changing our nature from sinful to holy. When the Holy Spirit works through us and guides our decisions, only then can we make Good choices for God pleasing reasons, and do truly good and holy works.
The work of Salvation. God in His Grace, (where Grace is not a thing, but reflects God’s favor), offers His own sacrifice for our Sin (which is Jesus, who is a thing). This is because, in our sinful condition, we are unable to offer an appropriate sacrifice of our own. (See above regarding selfish reasoning.) God in Human form, Jesus, (who is both man in form and God in spirit) sacrifices Himself for us. Upon Jesus' ascension, the Holy Spirit is revealed to us, and God continues to action His promise of Salvation via the Holy Spirit.
The order of Salvation. God, Jesus, Salvation, Holy Spirit, Baptism, Faith, Repentance; our own forgiveness of others; and then truly good and holy works on behalf of God, rather than on behalf of the selfishness of man. In this, good works are a consequence of Salvation, not a step toward salvation, and not a part of salvation. If there is one thing Lutherans must do in context of a work of salvation, it is to forgive others as Jesus has forgiven us.
The work of the Holy Spirit. The Holy Spirit does not simply dwell within us, the Holy Spirit infuses with our sinful spirit, cleansing our spirit to Holiness. There is no work on our part that makes this happen. This is a Monergist action on God’s part. From this point forward our will is now able to choose properly and we can now work with God in accordance with His direct guidance. This is in a more Synergistic view.
This view follows the pattern of Jesus, born both Physical Man and Spiritual God. We now exist in God’s likeness with the Holy Spirit cleansing our own spirit, while still maintaining our physical human and individual identity. We are still tempted by our flesh just as Jesus was tempted, yet we are now able to resist temptations as Jesus also resisted. Our flesh remains inherently sinful, but no longer controls our will to ultimate selfishness, rather repentance and faithful worship of God is reflected in our good choices and deeds.
Lutherans do not worship as a means to please God, nor do good works to please God. Lutherans worship and do good works as a means of thanksgiving and praise, because God is pleased with Christ’s sacrifice making us again worthy to be called His children, and be embraced by God in Heaven when we pass on from our earthly trials.
