A while ago I read that the difference between how men and women view morality is this (btw, if you wrote this let me know in the comments and I'll give you your backlink, I just don't remember which blog I read it from): men tend to have a moral system based on a set of rules, and women tend to have a moral system based on relationships and kindness.
A good Christian should keep both of these in mind. They should have a relationship with Jesus, and they should live by a set of rules which I will broadly call theology. The masculine sin would be to live according to theological rules without having any real relationship with God. Although I was not born at the time, from what I know of history, I believe that this was the Church's biggest problem in the 50s and before. That would explain things like the question in Times magazine: Is God dead?
Then through the sixties into our modern times we had a shift. Instead of focusing on theology in the church, we started to focus on relationship. Which is not a bad thing. The two greatest commands according to Jesus are to love the Lord you God with all your heart and with all your soul and with all your strength and with all your mind and to love your neighbor as yourself (Matthew 22:37-39). Not only that but Jesus also says of the two greatest commands that all the law and the prophets hang on these (Matthew 22:40). So, if you are living your life by following all the rules in the Bible: not having sex outside of marriage, not getting divorced, praying, fasting, the whole works, and you don't love the Lord your God, or love your neighbor as yourself; then you have nothing. Your religion is in vain.
The end result of the shift is that, at least in my experience, you have two kinds of churches today. One is basically just community centers that you go to every Sunday, and tend to not really have either relationship or theology. The second is the evangelical type of churches, where you do have relationship, but the theology is something less than rigorous. So instead of having leaders who intensely study the Bible, and draw the most honest conclusions that they can, even if those conclusions make them uncomfortable, you have movements where there is tons of intellectual laziness, and people are guide mostly by what they feel is right and staying true to themselves. And because they do this, they wind up not following the only two commands that they focused on, and in many cases, not living lives substantially different from many new age movements about positive energy or whatever.
Of course neither extreme is good and what you need is both. You DO need to love God and your neighbor. But when it comes to loving God, Jesus tells us: “Whoever has my commands and obeys them, he is the one who loves me”. So the way that we love God is by obeying His commands. And to obey his commands, YOU HAVE TO KNOW WHAT THEY ARE! And to know what they are requires theology.
