Seeking by a familiar spirit is anathema to God.
Christ Jesus taught to pray to the Father,
who is in Heaven.
'The meaning of "to pray" is "to ask".
Asking (praying to) any other entity in Heaven to intercede is disobeying Christ,
and opening one to demonic activity.
(NOTE: Though angels were sent from Heaven by God to speak to men,
NONE of those Saints anywhere in Scripture INVOKED them.)
The claim would be this is not praying to "her".
Why the "Amen"?
There is not even one instance in Scripture where any other being in heaven was invoked by godly folk.
They knew they were only to seek God for spiritual aid and mercy.
And this is not the same as asking someone on earth to pray for you.
Praying to any other entity in heaven is not the same as asking someone on earth to pray.
This is because when Christ taught prayers directed toward Heaven,
are to be prayed to the Father.
His teaching nothing to do with asking those on earth to pray for you.
