We sing the National Anthem to show respect for our country and for the men and women who suffered and died to protect our freedom. Who knows for sure, but it is worth checking out. Now, in the above situation we are speaking of respect for earthly traditions. Why not take it a bit further and talk on spiritual respect. Let's talk about reverence.
Reverence goes much deeper than respect.
And most of the time whenever we give reverence it is in relation to God. It could be for an office like that of the Bishop or that of the Holy Father. Or whenever we speak of God and use His name. All of these are to show the reverence and adoration we need to give to God. Lately, though, there seems to be a lack of these signs in the Church.
