The Baha'i Faith offers a variety goals, values, requirements, and prohibitions that influence and direct the behavior of followers. Baha'u'llah himself, a Manifestation of God whose word is considered infallible, dictated prohibitions against the following things related to the formation of a priesthood and various priest-like actions:
PriesthoodThe Baha'i Faith has no priests. While a particular person may lead Baha'i gatherings or be respected as religiously knowledgeable, they hold no official position in the religion and weild no official authority over their community.
The only infallible sources within the Baha'i Faith are Baha'u'llah, Abdu'l-Baha, Shoghi Effendi, and the Universal House of Justice. Beyond their writings, individual Baha'is are expected to seek out their own interpretations and understanding of religion. Thus, preists are unnecessary and even contrary to the Baha'i message.
This prohibition was influenced at least in part by the experiences of the Bab and Baha'u'llah with local Islamic leaders who objected to the injection of new religious teachings in the area. Islamic clerics pushed (and continue to still push in places like Iran) for Baha'is to be persecuted as heretics.

Asceticism And MonasticismWhile Baha'is consider material desires to be hurdles to spiritual development, they are forbidden from withdrawing from the world. Service to humanity is a primary goal of the Baha'is. As such, they need to remain engaged with the world, understanding the concerns of their fellow man, providing for the less fortunate, and fostering goodwill.
Confession of SinsThe confession of sins to another mortal in the hopes of divine forgiveness implies that others are better able to act as an intermediary between yourself and God.
"To none is it permitted to seek absolution from another soul; let repentance be between yourselves and God." (Baha'u'llah, The Kitab-i-Aqdas)
Kissing of HandsThis gesture would be familiar to Baha'u'llah as a gesture primarily used toward religious leaders, which Baha'is distance themselves from.
