There are many resources online for purchasing Catholic Saints Statues and Patron Saints statues.
Our Catholic tradition is that we have these statues near us to remind us of the grace filled lives of the Saints the statue represents.
Remember Jesus said He was the God of the living not the dead. I believe the meant the living as those in Heaven like the Saints in Heaven. They are alive and we keep statues around to remind us also of our future lives living with them in Heaven.
In additions, there are many sizes and styles of these statues.
We have assembled several resources in one web page for you to browse.
