Before the crucifixion is when Jesus was alive. Those who claim to have met him afterward either "heard a voice" (Paul) or didn't recognize him, which should alert any reasonable person's suspicions.
Yeah; like Thomas.
What suspicions should we be alerted to?
Luke 24: 28 And they approached the village where they were going, and He acted as though He were going farther. 29 But they urged Him, saying, “Stay with us, for it is getting toward evening, and the day is now nearly over.” So He went in to stay with them. 30 When He had reclined at the table with them, He took the bread and blessed it, and breaking it, He began giving it to them. 31 Then their eyes were opened and they recognized Him; and He vanished from their sight. 32 They said to one another, “Were not our hearts burning within us while He was speaking to us on the road, while He was explaining the Scriptures to us?”
36 While they were telling these things, He Himself stood in their midst and *said to them, “Peace be to you.” 37 But they were startled and frightened and thought that they were seeing a spirit. 38 And He said to them, “Why are you troubled, and why do doubts arise in your hearts? 39 See My hands and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have.” 40 And when He had said this, He showed them His hands and His feet. 41 While they still could not believe it because of their joy and amazement, He said to them, “Have you anything here to eat?” 42 They gave Him a piece of a broiled fish; 43 and He took it and ate it before them.
John 20:17 Jesus *said to her, “Stop clinging to Me, for I have not yet ascended to the Father; but go to My brethren and say to them, ‘I ascend to My Father and your Father, and My God and your God.’” 18 Mary Magdalene *came, announcing to the disciples, “I have seen the Lord,” and that He had said these things to her.
26 After eight days His disciples were again inside, and Thomas with them. Jesus *came, the doors having been shut, and stood in their midst and said, “Peace be with you.” 27 Then He *said to Thomas, “Reach here with your finger, and see My hands; and reach here your hand and put it into My side; and do not be unbelieving, but believing.” 28 Thomas answered and said to Him, “My Lord and my God!” 29 Jesus *said to him, “Because you have seen Me, have you believed? Blessed are they who did not see, and yet believed.”
Seems to be clear the above appearances were not a "heard voice" and they clearly recognized Jesus Christ and even examined the nail pierced hands and wound in His side.
I guess those five hundred people were delusional, too?
For what I received I passed on to you as of first importancea : that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Cephas, and then to the Twelve. After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born. (I Cor. 15:-8)
