Matt. 17:3; Mark 9:4; Luke 9:30 - Jesus converses with "deceased" Moses and Elijah. They are more alive than the saints on earth.
Matt. 22:32; Mark 12:27; Luke 20:38 - God is the God of the living not the dead. The living on earth and in heaven are one family.
Luke 15:7,10 – if the angels and saints experience joy in heaven over our repentance, then they are still connected to us and are aware of our behavior.
Mat 17:1 And after six days Jesus taketh unto him Peter and James, and John his brother, and bringeth them up into a high mountain apart:
Mat 17:2 And he was transfigured before them. And his face did shine as the sun: and his garments became white as snow.
Mat 17:3 And behold there appeared to them Moses and Elias talking with him.
Mat 17:4 And Peter answering, said to Jesus: Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles, one for thee, and one for Moses, and one for Elias.
Mat 17:5 And as he was yet speaking, behold a bright cloud overshadowed them. And lo a voice out of the cloud, saying: This is my beloved Son, in whom I am well pleased: hear ye him.
Mat 17:6 And the disciples hearing fell upon their face, and were very much afraid.
Mat 17:7 And Jesus came and touched them: and said to them: Arise, and fear not.
Mat 17:8 And they lifting up their eyes, saw no one, but only Jesus.
Notice here that Moses and Elias are right there, Jesus did not call out to the wild blue yonder for them. Though He could have as He is God.
Mat 22:29 And Jesus answering, said to them: You err, not knowing the Scriptures nor the power of God.
Mat 22:30 For in the resurrection they shall neither marry nor be married, but shall be as the angels of God in heaven.
Mat 22:31 And concerning the resurrection of the dead, have you not read that which was spoken by God, saying to you:
Mat 22:32 I am the God of Abraham and the God of Isaac and the God of Jacob? He is not the God of the dead but of the living.
Jesus was correcting the Sadducees, the Sadducees did not believe in angel, demon, resurrection or afterlife of any kind. I wonder why scripturecatholic does not mention that? Also note that He is comparing the not marrying with the angels, does not say people will be like angels in every aspect.
Luk 15:7 I say to you that even so there shall be joy in heaven upon one sinner that doth penance, more than upon ninety-nine just who need not penance.
Luk 15:10 So I say to you, there shall be joy before the angels of God upon one sinner doing penance.
Luk 15:1 ¶ Then drew near unto him all the publicans and sinners for to hear him.
Luk 15:2 And the Pharisees and scribes murmured, saying, This man receiveth sinners, and eateth with them.
Luk 15:3 And he spake this parable unto them, saying,
Luk 15:4 What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it?
Luk 15:5 And when he hath found [it], he layeth [it] on his shoulders, rejoicing.
Luk 15:6 And when he cometh home, he calleth together [his] friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost.
Luk 15:7 I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
Luk 15:8 ¶ Either what woman having ten pieces of silver, if she lose one piece, doth not light a candle, and sweep the house, and seek diligently till she find [it]?
Luk 15:9 And when she hath found [it], she calleth [her] friends and [her] neighbours together, saying, Rejoice with me; for I have found the piece which I had lost.
Luk 15:10 Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth.
This is talking about the angels rejoicing.
