What is "reformed" ?

i am forever returning to this quote to broaden my understanding of what it means for a Christian or a church to be "reformed".....
“It’s a style of life that gives prominence to
the conviction that God is creator; hence it is that
we give thanks to God for the goodness that surrounds us. Secondly, it incorporates a deep and powerful sense of the fallenness of all things, understood in such a way that there is a strong impulse to resist all attempts to draw lines in the
sand, with the explanation that human fallenness occurs on this side of the line and not on that side of the line. Fallenness runs throughout our
entire existence—indeed, through the cosmos.
Corresponding to this comprehensive view of sin is then an equally comprehensive view of faith and salvation... In short, I think that at the heart
of the Reformed tradition is a passion for totality, for wholeness, for integrity, for not allowing life to fall into bits and pieces but to constantly ask,
‘What does my faith—what does the gospel of Jesus Christ—have do with this and what does it have to do with that?’ And then never being content with the answer, ‘Nothing!’”
