Familiar Spirits.

Lutero said:

Praying to the saints is the sin of praying to  "familiar spirits" is what it is, and it is strictly forbidden by God saying thus directly to Israel;

Scripture says:

Luke 16:24
And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame.

(Lev 20:6) And the soul that turneth after such as have familiar spirits, and after wizards, to go a whoring after them, I will even set my face against that soul, and will cut him off from among his people.

We don't do that. We simply love the Saints which God loves and we acknowledge that they have received the promises which God made. We also acknowledge that they are alive in Christ.

Hebrews 6:12
King James Version (KJV)
12 That ye be not slothful, but followers of them who through faith and patience inherit the promises.

1 Corinthians 15:22
King James Version (KJV)
22 For as in Adam all die, even so in Christ shall all be made alive.

Sincerely,

De Maria
