be supported by remote tradition alone

[jacob123]

What does "remote" here mean? Does it mean "old"?

I venture now on a bold saying; for I predict that, in consequence of the new evidence, all reasonable men, a century hence, will believe the Resurrection of Christ, whereas, in default of the new evidence, no reasonable men, a century hence, would have believed it. And especially as to that central claim, of the soul's life manifested after the body's death, it is plain that this can less and less be supported by remote tradition alone; that it must more and more be tested by modern experience and inquiry.

That's how I understand it.
