Through his religious education every mature Christian ought to be able to distinguish between the actual dogma of the Church and
theological opinions that may be
changed and improved, between immutable divine law and changeable human law.
What has happened in contemporary research is that
opinion with regard to the synoptic gospels has moved nearer, concerning their
theological motivation, to what
opinion with regard to the fourth gospel always has been, without
opinion with regard to that gospel
changing significantly.
