Jesus once told us that "from the heart, the mouth speaks". That means that what we really believe is seen in our words. What are your words like? Do you generally speak with love and encouragement? Or, do you generally speak with contempt and discouragement? You do not need to get a tally sheet to figure out which it is. You know what your behavior is like and what words you use.
Now, let us apply this to how we speak about the Pope (and other clergy). What is the majority of the content in your speech when you talk about Pope Leo? We all have to admit that Pope Leo is more traditional than Pope Francis ever appeared to be. And, we also must admit that there are times when Pope Leo says something that makes us curious about how traditional he is.
It is not wrong to express a disagreement with the Holy Father (in fact sometimes we must express that disagreement). I am more asking about how often do you say something that shows love for him, as compared with how often you say something that shows discontent? If the latter is most common for you, then you very likely are not honoring properly. Jesus told us that we will say what is already in our hearts. If anger against the Holy Father is what you say the majority of the time, you have given in to this error.
Thus, you need to work on filling your heart with love and holiness. Then you will be able to speak about the Pope (and anyone else you might be upset at) with love and holiness. You do not need to agree with the Pope to speak with love and holiness about Him; you just need to be humble and loving in regard to your disagreement. There will always be times when it is hard to maintain godly speech, but the Lord told us how to remedy that. His ways are always best, so let us each make sure that we do whatever we can to purify our hearts, so that when something slips, it will be righteous.
