Modern society (including morality) is based on HUMANISM. God has been abolished long time ago.
In the past, people went to the priest and asked him what is good and he would tell them "Homosexuality is bad because God says it is bad, or the pope says so." Nobody cared what people thought. But today, people don't care for what God says, or the Bible, or the Pope. What is authority today is what people think and feel. Now, there are some harder ethical questions that need further discussion, but they are all centered around human feelings and thoughts, no one takes out the Bible and looks at what the divine commandments say.
God lost authority in politics - it was considered that bishops had all the answers from their holy books on how to run a country, but now with humanism, it is considered that human feelings are the most important. So you have the voter deciding what is best for the people and you don't ask God or the Pope. You go to each human and ask him or her what they want. You don't go anymore and tell people "Yes, you might think that and feel this, but you are wrong because there is a higher authority saying that you are wrong," like it was in the middle ages, and is in now Islamic theocracies.
God out of education - people were used to be educated on what God supposedly thinks so that they project that into the society, but today people are educated to think for themselves because thinking for yourself to know what you want is the highest part of the authority in a democracy.
And so on.

teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
