There is Scriptural warrant for such worship in the passages where we are bidden to venerate angels (Exodus 23:20 sqq.; Joshua 5:13 sqq.; Daniel 8:15 sqq.; 10:4 sqq.; Luke 2:9 sqq.; Acts 12:7 sqq.; Revelation 5:11 sqq.; 7:1 sqq.; Matthew 18:10; etc.),
Not one of these passages tells us we are to venerate angels. Not one.
We do have passages though where angels do tell us not to worship them.
Rev 22:8-9 NASB
And I, John, am the one who heard and saw these things. And when I heard and saw, I fell down to worship at the feet of the angel who showed me these things. And he said to me, "Do not do that; I am a fellow servant of yours and of your brethren the prophets and of those who heed the words of this book; worship God."
The angel understand that bowing down/falling at the feet of the angel was worshipping him and he quickly corrected John's error.
whom holy men are not unlike, as sharers of the friendship of God. And if St. Paul beseeches the brethren (Romans 15:30; 2 Corinthians 1:11; Colossians 4:3; Ephesians 6:18-19) to help him by their prayers for him to God, we must with even greater reason maintain that we can be helped by the prayers of the saints, and ask their intercession with humility. If we may beseech those who still live on earth, why not those who live in heaven?
This is a supposition based on human reason based on a false assumption as noted above.
All of the examples noted were Paul asking real people to pray...people here on earth. Our departed loved ones cannot hear us. We have no injunction or example in the New Testament to pray to our departed loved ones.
Ummm... what are you talking about? I see no reference to angels anywhere in here.
