I don't think the Pope said anything President Monson wouldn't say.
The article says he changed no doctrine. He wasn't throwing out teachings
on abortion or traditional families. He was saying not to make them gospel
hobbies--a caution Mormons often receive from their own leaders. The centrality
of the gospel is the atonement and that should be the bulk of our preaching. The
other issues are important, but must be taught in a context of love and
acceptance. We have to judge the action and not the person, just as Jesus did
with the woman caught in adultery. When we preach a gospel of love, we have a
greater chance of bringing about true conversion. Jesus warned people that
getting caught up in the details took them away from the true message of
salvation and that is what the Pope was warning against.
And if you read his comments in context, you will realize that there is being
made much ado over nothing. Go search for the interview and find the spot where
he talking about this and you will see what I mean.
