Of course there is not one dimension of spirituality, as we are all unique. What the priest was trying to convey to us back in our aspirancy year was that we need to try and touch all people with our preaching. The problem is, you will never be able to do that all the time. Some people are distracted, some people just may not connect to the Good News, some people will get it, and all the other myriad variations on this.
I just pray to the Holy Spirit for guidance each time I sit down to write my homilies in formation and I try to look at the text in a fresh and naive way (meaning, I try and let go of all the preconceived ideas I have of the text). I ask myself the question on how this text has touched me? What am I excited about in this passage? What questions do I have? I try and then concentrate on one specific and clear message. I want to create a spiritual experience for the listener. This is about formation not information. I also want to SHOW them the Good News, not just tell them what it is. Give this some skin meaning, give it life, show it in real life… their lives, my life, someones life. This means make the homily relevant to them… and relevance is what is most lacking in many homilies (those that do not connect to us).
I don’t claim to be an expert, and have been only doing this a short time, but I found that with prayer and trusting in the Holy Spirit, and doing the steps above and others I can help connect the Word of God to those who are listening. It is challenging and I often doubt my abilities, but if I do this, I trust my homily will connect with as many people as possible.
