the pca takes the following position on homosexuality: "homosexual practice is sin. the bible teaches that all particular sins flow from our rebellious disposition of heart. just as with any other sin, the pca deals with people in a pastoral way, seeking to transform their lifestyle through the power of the gospel as applied by the holy spirit. hence, in condemning homosexual practice we claim no self-righteousness, but recognize that any and all sin is equally heinous in the sight of a holy god." the pca opposes same-sex marriage. l. roy taylor, stated clerk of the general assembly of the pca, has said that the pca "believes that, from creation, god ordained the marriage covenant to be a bond between one man and one woman" and that "divinely sanctioned standard for sexual activity is fidelity within a marriage between one man and one woman or chastity outside of such a marriage. throughout history, there has often been a conflict between the unchanging standards of biblical ethics that the church seeks to maintain and the changing social practices of the culture."
