Does love for your children divert love from your spouse?
Catholic Church was Founded by Christ... do you really think he would allow Saints and the Rosary and the Like without his blessing. More is expected of Catholics it is a Real Shame that Non Catholics Miss the Body Blood soul and Divinity of Christ in Communion! Confession having your sins Forgiven by Christ representative on Earth. Too experience St Faustina first Saint of the 21st century in the 1930’s writing a Diary as Commanded By Jesus Christ Himself about what Makes him Happy and Sad on Living our lives on Earth. He also mentions in the 1930’s that the Slaughter of the Unborn Innocents is the Most Horrendous crime of all time. That was when Margaret Sangor set up the Family Birth Control League the precursor to Planned parenthood.
The catholic Church was the ROCK that has always stood Firm against SIN like Abortion.. and Many Other sad situations accepted By our secular Society and The Moral relativist. Gang! The Manmade Religion followers suffered as a result!
Prayers to saints are prayers to God. It is by His power that they are saints and work miracles. If God did not want you to venerate them, He would not grant them a single miracle.
However, it is possible to pray wrongly. It is possible to pray wrongly to God directly; it is possible to pray to a saint wrongly. If, in the hypothetical example that you offer, a prayer to a saint is a diversion, then one should not pray that and find a better way to pray.
Christ gave us an example of that. When a woman in the crowd cried out “blessed is the womb that bore You and the paps that gave You suck”, her veneration of Mary was sincere but a bit imprecise. It was stressing physiological motherhood. But Jesus wanted us to venerate all saints rather than His mother alone, and He wanted us to venerate them for reasons of their obedience to Him. So He corrected the woman: “Yes, rather blessed are these who hear the Word and keep it” (Luke 11).
