What is objectively good is known by God, and was revealed by His Gospel on earth, obviouisly, is the only proper Christian response.
It also is true that many people, without God, have some idea of the good, and know what the good is to a very clear degree, and this is because they are ikons of God.
The "culture" or the "times" never dictate what is moral or virtuous, or what is a vice.
This is because cultures and times and periods tend to produce their own vices that they deem as necessary for having a comfortable, managed society, and they just throw their hands up and say "oh, this is how it has to be" whenever they are questioned on it too much for their own liking.
