I had it explained to me like this while I was converting from Baptist to Catholic:
“We don’t pray* to *saints; we ask them to pray for us to Jesus”.
There’s a big difference!
This helped me a lot when I was trying to understand the concept of asking saints to pray for us.
It’s like asking a good frined or family member here on earth to join with you in prayer for your needs, only we are asking the saints in heaven to pray for us instead.
