If there is an absolute truth then you can’t have subjective morals. If I were to ask two people a math problem and they give me two different answers, they are not both correct. In scripture we have everything we need to know what is right. The fact that people interpret them differently is not an indication that the morality of the Word is subjective. This does not mean that people who interpret the Bible incorrectly are evil, just that they are in need of guidance. That is what is wonderful about the Church. When we are unsure of something we have people to go to. I can talk to a priest at any time to help me understand my faith. There is nothing wrong with not knowing everything, unless we let pride blind us into believing we have a better understanding than we really do.
