You have a great deal of misinformation regarding the role of icons, saints and Mary.
And These have turned into three popular areas for attack by you Aieno and protestant groups. The idea that Catholics worship idols is wrong, but it is a common notion among many.
I explain icons and statues this way. They are physical reminders of our faith. We do not worship them. They are meant only to remind us of what we believe. We do not worship the crucifix; we look at it. We acknowledge it as a sign of how Christ gave himself for us.
Whats wrong with a Crucifix? Please show me if theres anything wrong with a Crucifix in Biblical light. We all know Jesus is no longer there, but that Crucifix is the fundamental point of Christianity. And reminds us of his Sacrifice.
If that is too complex, how about an example from the office. I have a calendar and post-it notes, which I use to remind myself to do something. I will write a note to call my wife. If I look at the note and read it, does that mean that I have called my wife? No! The note is a reminder. By reading the note, I have been reminded.
If I look at a statue of St. Thomas, have I worshipped that statue? No! But, perhaps I am reminded of the work he has done in the church.
That brings me to my second point. Saints are not an object of worship for the Catholic Church. They are examples of people who have lived their lives as Christ would have them live.
The Church has seen fit in its history to honor certain people with canonization as saints. These people do not become gods; they become examples to others. Jesus said, "You shall love the Lord, your God, with all your heart, with all your being, with all your strength, and with all your mind, and your neighbor as yourself" (Luke 10:27). Saints are individuals who have best followed this commandment. We honor them to remind ourselves of what we should strive to do and be like.
We hold saints to be those individuals who most closely lived their lives according to their faith. By revering them, we hope to inspire ourselves and to educate ourselves as to what exactly Christ meant when he gave his commandment.
I'll use another analogy. If you want to study plant life, you can go outside and stare at the plants, pull them apart, analyze them, and make general conjectures upon what you have observed. However, others before you have done this. How many science classes do you know of that have skipped the textbook and gone straight into the lab without any guidance? The best way to study plant life is to read what has been written and then to expound upon that with your observations.
As Catholics, saints are our textbooks. St. Augustine, in his Confessions, tells us what it means to repent your sins and to modify sinful behavior. Our response to this is not to worship St. Augustine. It is to say "Thank you. You have given me something to think about." We then will go and try to emulate what he has done, which is what Christ called us to do.
Complete emulation of a good person will result in a good person. Why is that wrong?
Peace
