Is it lawful to invoke the intercession of a Servant of God

[mythbuster1]

Or does the intercessor have to be at least a Venerable?

 

[po18guy]

Huh? If you can ask a living Christian to pray for you, you may certainly ask someone reasonably expected to be in heaven or on their way to pray for you.

 

[JimG]

It must be ok to ask their intercession. If they are to be declared a saint, there will need to be evidence of miraculous intercession.

 

[Tis_Bearself]

In your own personal prayers, you may ask for the intercession of any deceased person whom you reasonably believe is in Heaven. Obviously this would include Servants of God, since they have a sainthood cause and would not have even made it that far if they weren’t reasonably believed to be in Heaven.

Public devotions to a Servant of God, such as a prayer group meeting at your church asking the Servant’s intercession or a large group novena to them on the Internet, requires permission from an appropriate ecclesiastical authority. For a group at your parish, you’d get permission from the parish priest. For a group in a diocese, you’d get permission from your bishop. Etc.
