According to the author, if one's religious moral code gives conflicting advice on whether it is permissible to drink alcohol, then moral philosophy cannot provide any guidance because the conflict can only be resolved by interpreting religious texts

In the case of a religious moral code that provides conflicting information as to whether or not it is permissible to drink alcohol for an individual, reading more religious texts may make the information even more conflicting for the individual to interpret. In this case, the ideal is that the individual seeks guidance from someone who knows that code more fully and can show a new interpretation of the information, but what will determine whether or not the individual can consume alcohol is the relationship between philosophy of this individual with the information of the code.

That is, in a situation of conflicting information, what will determine what the individual should do is their moral philosophy about that subject. This is because moral philosophy will determine a set of values that point to what characterizes a life as being good in the conception of an individual.
