Two Angels or two men?
Could two men have rolled the stone from a sealed tomb which would be very much a boulder.
50 Jesus, when he had cried again with a loud voice, yielded up the ghost.
51 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;
52 And the graves were opened; and many bodies of the saints which slept arose,
53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
When Christ died his death caused the saints who had died at that time to rise.
If as a none believer you knew he healed the sick, raised the dead and even the dead saints raised at his own death. What would the account of those who wrote about these things for
the believer really matter to you? The fact is that useless arguments lead nowhere and are unfruitful
King James Bible Titus 3:9
But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
The truth about Jesus Christ (as acts 10) show are the only facts that matter.
People are not raised from the dead about who rolled the stone away or the first witnesses. It is the love, power and truth about Jesus Christ and God which are important to believers then and
now. Useless arguments such as above will never result in anything positive for believer or atheist. You just have to accept the fact it is Christ or no way.
