What, if I may ask are your doctrinal differences and views in relation to that of the Christian.
I did read a little of your roots but never found the mention of :
It seemed they emphasized adherence to a system rather then conformity to a diety
They were more or less an organization then a church of God
Could you expound a little
well, like i've said, Quaker beliefs are pretty diverse, but i'll try to give you an outline based on the Hicksite Quakers' beliefs i'm most famialr with. also be aware that many of the terms you've mentioned above just aren't part of Quaker theological speak, but i'll do my best. warning: gross generalizations ahead!
salvation and blood- many liberal Quakers understand living a simple, pious life style as its own salvation. there is not alot of emphasis placed of Jesus' death as a means of salvation, as Quakers tend to focus more in Jesus' life and teachings then his death.
sin, atonement, redemption- Quakers generally believe that sin results from not listening to the voice of God's love within us, from acting selfishly and judgementally based on this shutting out of God's voice. there is no formal process of atoning for sins, though during meeting some Friends will rise and voice concerns that they are struggling with to the congregation, and ask that they pray for them in their striving for the right path. Quaker's generally don't believe in orginal sin and beliefs vary as to the role of Jesus as a saviour of souls. many Quakers see the teachings of Jesus, however, as a model for a simple life of love and service lived close to God, which in its own way is spiritualy redeeming in this life.
judgement- few Quakers tend to see God as a judge, more of a subtle spirit. Quaker beliefs about the afterlife vary, though the general idea is that good deeds and love matter more in the end than creed.
righteousness- the Quaker ideal of livelihood is one based on simplicity, service to others, pacifism, and striving to hear God in all aspects of life. i think that's pretty much the running definition of Quaker righteousness.
holiness- ah, this one's tricky. well, God is surely holy. but many Friends would also contend that all aspects of life are holy, and that all human life is holy, as well. which is not to say that the concensus is that God is synonymous with all things, no. but God is with all things and people, and His influence and guidance can be witnessed and heard if one uses the open senses of the spirit.
sanctification- could you clarify this term some? see, this is one of those terms i'm just not familiar with within the context of Quakerism. what is being sanctified?
ok, i hope that helps a little! appologies if i've confused things further (that does happen sometimes!) let me know what else i can try to answer!
