We Baha'is would probably say there's a "middle ground" between the concepts of Avatara and Prophets...
An Avatar is sent to the world when mankind is in greatest need:
"Whenever there is a decine of dharma O Bharata and rise of adharma I incarnate Myself"
Similarly a Prophet appears when man is in desparate straights...
The Manifestations of God we believe do this... They are from their inception pure burnished Mirrors that reflect the Divine Attributes.
To quote Baha'u'llah:
These sanctified Mirrors, these Day Springs of ancient glory, are, one and all, the Exponents on earth of Him Who is the central Orb of the universe, its Essence and ultimate Purpose. From Him proceed their knowledge and power; from Him is derived their sovereignty. The beauty of their countenance is but a reflection of His image, and their revelation a sign of His deathless glory. They are the Treasuries of Divine knowledge, and the Repositories of celestial wisdom. Through them is transmitted a grace that is infinite, and by them is revealed the Light that can never fade These Tabernacles of Holiness, these Primal Mirrors which reflect the light of unfading glory, are but expressions of Him Who is the Invisible of the Invisibles. By the revelation of these Gems of Divine virtue all the names and attributes of God, such as knowledge and power, sovereignty and dominion, mercy and wisdom, glory, bounty, and grace, are made manifest.
