Its not a vain repetition. It’s the most beautiful Litany known to man. And for those who have gone to Jesus, holding Mary’s hand, it’s comfort and strength. Like when I was little and my mother would smooth my hair back behind my ear with a touch filled with love. She did it gently, repeatedly.It let me know I was loved. It calmed me. It made me feel secure. It comforted my heart. We comfort the Lord’s heart and offer great consolation when we offer Him this prayer, so loved by His gentle and Holy mother. We love her. She loves us. Mary is never the end or the goal. Jesus is. And even if you tried to make her the goal, it would never work. She ALWAYS takes her children and leads them to Jesus - always. She speaks wisdom… “Listen to Him. Do whatever He tells you.” Jesus is Mary’s God too. Even the Angels in the old testament yelled at the men they would appear to if they fell on their faces to worship them, as they are not God. Mary is the Queen of ANgels. She would absolutely NEVER tolerate anyone giving to her what can only be given to God. You can certainly pray to the Holy Spirit and you should. He’s God. The third person in the Holy Trinity. The fountain of all wisdom. The promised Paraclete. Our Love, Our Creator. There is no sin in worshipping God. Only in worship of ANYTHING that is not God. And every time you glorify the Son, you glorify the Father and the Holy Spirit. They are eternally and indivisibly One. If you have worshipped Jesus, you have worshipped the Holy Spirit, and that is as it should be. So, be at peace. Latia (worship) = for God alone. Hyper dulia (the highest veneration) for the Great Mother of God, Mary most holy. Dulia (respect / veneration) for Saints. Dulia and Hyper dulia are not worship. Worship happens in the heart and no man can read the heart of another. I kneel at my bed to pray. I do not worship the bed. I hang pictures of my family in the hall and when I miss them, I look at them and think of them and give them a call. Respect… devotion… not worship. But, we DO worship the Holy Eucharist - Immanuel, God with us, His body and blood, soul and divinity, truly and physically present in the Eucharist. And that is also good, right, and correct so never worry about that because we are called to worship Him.
