Praise be to our Lord Jesus Christ.
Whatever our beloved Pope said is the theme of our life. It is so wonderfully said.
By the following, I do not want to side-track or undermine our Pope’s words. They are very beautiful, short and profound.
In relation to this topic, that is of the referred “heart”:
When I was a child/teen, 25 years ago, I used to hear this verse in the Church.
The kingdom of heaven is in your heart. When I searched for this verse few years ago, I do not find the word “heart” in there.
If you now put this verse in the internet, you can see lots of articles popping up. Most of them are in the manner of trying to explain why it is not entirely in our heart. Most of them assume that we could go wrong with this verse. Well, may be.
There are two extremes to this context, I mean, in using this verse in one’s life. One is in the manner of supporting the (recent) ideology of self realization, God-less meditation/yoga/etc., as finding the kingdom of heaven. This extreme is the most dangerous one I believe. This sometimes makes even atheists to feel like they are good without God and our Lord Jesus Christ. This also lets many others, who think they do not need God to be good, and/or who thinks that Love is God, to feel that they are the correct ones in the manner of accusing Christ-ians wrong.
Another is supporting the ideology of totally outward living through not defending the word “heart” in this verse. I mean going more on the outside of oneself as well. Like it is only in a (specific) church or in a gathering where Christians are together or among 2 or more Christians, and NOT anywhere else.
I believe, both of the (extreme) interpretations are mostly used to defend their (current) way of life and most importantly to proudly continue in it, not welcoming progress and the conversion if needed any, and so ignoring everything else to favor their own way, and possibly also in judging and/or accusing others. May be there are few pure intentions too.
However I found an article online, by Ilaria Ramelli. It is interesting.
Our Father who art in heaven, Hallowed be Thy name. Thy kingdom come… Amen.
