Each gospel
account records events from different perspectives. Matthew
and Mark mention one angel (Matthew 28:2–7; Mark 16:5–7), whereas Luke and John
mention two (Luke 24:4; John 20:11–12).
In the Matthew
and Mark accounts, the focus was on the angel who was speaking. This doesn't mean another angel wasn't there, but the accounts record what just one of them said.
Perhaps he was the main speaker, as Luke and John also recorded what the angels said, but recorded it as if both angels were speaking to them. Putting the
accounts together, the message was from both, though only one spoke it. The minor differences in the Gospel accounts do not show contradictions and prove that there was no collusion to make each account "match" perfectly.
"Gotcha questions" are the bane of any student, job applicant, or tired parent. Christians, though, are used to getting "gotcha" questions from unbelievers who point out supposed "contradictions" in the Bible with the goal of undermining the credibility of Scripture. The number of angels at Jesus' tomb is an example of this.
But if all four gospel accounts were exactly the same, that would be suspicious and cause people to think the writers colluded. The Holy Spirit worked through men to write the Bible, and He didn't make these men into robots. Each had different writing styles and emphasized different details of the same accounts.
The Bible is inerrant in everything it contains. That means that whether one Gospel shows one angel and another shows two, both are accurate and not mutually exclusive. What's even more important is that the angel’s
message changed world history because it announced the Savior
whom death could not hold (Acts 2:24). Ever since that day, the world has been
scrambling to either tell others about Jesus’ resurrection or to deny the empty
tomb. We could argue on the exact number of angels or recognize that the real question isn’t how many angels were there but what we will do with the message they proclaimed. Will we trust in the risen Christ and follow Him, or try to explain away the very event that changed everything?
When closely examined, the supposed Bible "contradictions" can be resolved, and none of them change the main and plain message of the gospel: "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life" (John 3:16).
