The following is an excerpt from what was published in the April 15, 2019 edition of Weekly Diocesan News from the Office of the Bishop, without explanation:
Diocese of Sacramento Guidelines for Selecting Outside Speakers Parishes, Movements, Apostolic Groups, Catholic Schools
It is the responsibility of the hosting party to present a list of potential speakers. The Diocesan Bishop will make the final decision. In most cases, the bishop has appointed the Director of the Office of Clergy Formation to gather and review all required information and make a final decision.

General Rules on Speaker Stipends and Sales
Under no circumstances is the speaker allowed to request a donation or take up a collection (Note: Violations of this rule may result in the suspension of faculties of the speaker in this diocese and the host may lose the authority to create or host future events).
Provide an environment that supports learning (space and materials) As a general rule, the invitation of any speaker or honoree should be an opportunity to evangelize and catechize the faithful. Thus, anything which may cause confusion or scandal or incite to disrespect or dissent is to be avoided. Remember that when a speaker is assessed, Diocesan Statute #81 must be followed: Any speaker who publicly promotes or advocates views which are contrary to Church teaching, may not give a talk, retreat, workshop, course, etc., at Church related events, or on church, school or diocesan property in the Diocese of Sacramento. Likewise, anyone who publicly promotes or advocates views which are contrary to Church teaching may not be given awards, honors, or other marks of public recognition.
