The word "pray" in its original and most authentic sense, is only encountered in 3 places in America today:
If anyone in fact adored a civil court; or a would-be lover; or Mary and the other saints, it would in fact be idolatry. But we don't. We do not adore anyone except the Father, the Son, and the Holy Spirit. To the Holy Trinity be glory forever, Amen.
In a court of law ("The appellant prays this honorable court...")
In Shakespeare and other Elizabethan-era authors ("I pray you, do not fall in love with me")
and in Catholic intercessory prayers.
While that may be true (in some cases in your religion), it certainly is not an accurate description of most of the other cases of prayer in your religion...
The English word pray has another original and authentic meaning...It is derived from a different Greek word with a different meaning...You forgot to add that...So lets look at a couple...
Luk 14:18 And they all with one consent began to make excuse. The first said unto him, I have bought a piece of ground, and I must needs go and see it: I pray thee have me excused.
Is this how you guys pray to Mary and your Saints??? Pray, as a request...
G2065
ἐρωτάω
erōtaō
er-o-tah'-o
Apparently from G2046 (compare G2045); to interrogate; by implication to request: - ask, beseech, desire, intreat, pray. Compare G4441.
Luk 21:36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
Or is this the one???
Pray, as a request...
G1189
δέομαι
deomai
deh'-om-ahee
Middle voice of G1210; to beg (as binding oneself), that is, petition: - beseech, pray (to), make request. Compare G4441.
Pray, to God only, as as the example in the NT scriptures...
1Ti 2:8 I will therefore that men pray every where, lifting up holy hands, without wrath and doubting.
G4336
προσεύχομαι
proseuchomai
pros-yoo'-khom-ahee
From G4314 and G2172; to pray to God, that is, supplicate, worship: - pray (X earnestly, for), make prayer.
Lifting up holy hands...Kind of similar to kneeling or proning oneself to a statue of Mary or a Saint and asking that they perform miracles and provide salvation and well being as only God can do???
I'd say from the Bible definition, that your prayer to your Saints and Mary is nothing less than, Worship...
