Isabella Chow, a senator within the Associated Students of the University of California (ASUC) body, has been disaffiliated with the Student Action party following her comments.
During an ASUC debate which touched upon gender identity, Chow said she believed God created man and woman and that marriage should only be between one man and one woman.
She was quoted by The Daily Californian news website as saying: "I cannot vote for these bills without compromising my values and my responsibility to the community who elected me to represent them.
"As a Christian, I do believe that there are certain... lifestyles that conflict with what is good, right and true."
The business and music student added that she loves all people and all identities are valid.
Fellow senator Teddy Lake, an advocate for members of the LGBTQ+ community, was quoted by The Daily Californian as saying: "I don't feel comfortable being told that I'm valid and then saying that you disagree with me and my community."
Student Action suggested Chow's views on abortion were another attributing factor to her being dropped as a party representative.
In a statement posted on Facebook, leaders said: "As a party, we are committed to ensuring that the rights and dignity of the queer and trans community on this campus are guaranteed...
"As a party, we are committed to establishing and defending access to reproductive health services.
"This is why we, as a party, have resolved to part ways with ASUC Senator Isabella Chow due to inconsistencies between her beliefs and the mission of Student Action."
Premier has contacted Isabella Chow for a comment.
