I am advocating that the Church change to recognize new revelations of the universe God created, new understanding of humanity and nature, of how we can live together, of how we need to nurture our Mother Earth rather than conquer it.  God lets us grow in understanding - it is a part of evolution.   We are not perfect, are not all God intended us to be, not only by sin but also because God's evolution is taking us some place.  

Much of what you think is God's will is human attempts to decipher the infinite.  What we should not do is freeze that understanding as it came to be in a particular time as if it would be true for all time.  Jesus taught us God's love is infinite and we are called to love one another.  The rest is open to translation.  

The Church has spent 2000 years developing doctrine and understanding.  It is a big mistake to think they always got it right or that what was right for one time is right for all time.  Culture evolves, too.
