Why wouldn't she answer a question the answer to which has a bearing on the salvation of my soul? Or did she perhaps think the question too stupid and the answer self-evident? I'm not trying to be flip, but just throwing out some thoughts that went through my head.
First, whether Francis is pope or not has no bearing on the salvation of your soul. Your salvation depends upon you persevering in the faith till your last breath so you can die in the state of sanctifying grace.
Second, suppose you received a rose from someone - does that mean you now know Francis is pope? Will you become Novus Ordo and do what NOers do and attend the new "mass", CITH, contracept, divorce/remarry, etc. ad nausem? IOW, do you suppose if you received a rose you could now sin without fear of punishment because Francis is pope? St. Therese is not going to be responsible for that.
Don't be solicitous for something harmful to you and expect heaven to answer.
"Seek ye therefore first the kingdom of God, and his justice: and all these things shall be added unto you. Be not therefore solicitous for tomorrow; for the morrow will be solicitous for itself. Sufficient for the day is the evil thereof."
