>One of our main beliefs is that, from time to time, God sends Messengers to guide mankind. These messengers include Jesus Christ, Abraham, Moses, Buddha, and others; and in more recent times (after Christ), Muhammad, the Báb, and Bahá'u'lláh. (The latter two are considered the founders of the Bahá'í Faith.)

>Nor do I think that this means that God will send no prophets after Jesus Christ. In fact, Jesus speaks repeatedly about His return.

Interesting. Christians beleive the last prophet to be John the Baptist. Hebrews 1:1-2 strongly implies there will be no more prophets - in fact much of Hebrews (esp chapters 9 & 10) explains why (ie, Christians now have direct access to the Father through the Holy Spirit). Jesus was not a prophet, although he was mistaken as such by some people of his time.

>In the time of Jesus Christ, all mankind was supposed to turn to Him. Perhaps this is what the verse you mention refers to. I do NOT think that this means that all prophets that came before Jesus Christ were fake (for instance, Moses), or that their laws were invalid at their time.

No one is saying Moses or any of the Prophets of the OT were fake. The Old Testament (and the Prophets) point to Christ.
