Hint: We’re under the New Covenant.
What means “dead”?
Were Moses and Elijah “dead” when they appeared with Christ in front of Peter?
Those passages very much confirm my point.
**Were Moses and Elijah dead when they appeared with Christ in front of Peter?**
And what did Peter do?.....he got the idea to worship, venerate (or whatever you choose to call it) all three equally, in suggesting that he, James, and John, build tabernacles for Jesus, Moses, and Elijah. But in short order, Moses and Elijah disappeared, leaving only the Son for them to focus on.
Those passages very much confirm my point.
As for the element of them being "alive" ---the concept and argument of that being opening for doctrines both allowing AND advising "asking for prayers" from persons (saints, even) who have departed from earthly living realm, to be comparable to requests for prayers directed to those who are known to us still living upon earth (not in Heaven, but still with us upon the earth), doesn't fly, it tries (tried to), but instead melts under the heat of closer examination of the Scriptures, reminiscent of Icarus flying too close to the sun.
Daddy tried to warn Icarus...
Our Father in Heaven, speaking through His begotten son, Jesus, tried to tell us in unspoken manner -- do not-- (the negative aspect) when telling us so when when Jesus told his disciples otherwise, "do", telling them to :In this manner, therefore, pray: Jesus said, providing positive model of how to pray what's come to be known as the Lord's Prayer (Matthew 6: 9-13), the 'Our Father'.
As towards the unspoken argument I have just now alleged Jesus made (which is; do not direct prayers heavenwards to anyone other than the One True God) feel free, knock yourself out, take again wing and go soaring to find for us doctrine originating from within Scripture itself that proposes such as you suggest.
Flying over waters (of the deep?) may be better than flying over land. It (water) can be softer to fall into than upon dry, hard, stony land. Would help to be able to swim though...
