the pca is more socially and theologically conservative than the pc(usa). the pca requires ordained pastors and elders to subscribe to the theological doctrines detailed in the westminster standards, with only minor exceptions allowed, while the pc(usa)'s book of confessions allows much more leeway. the pca ordains only men who profess either traditional marriage or celibacy, while the pc(usa) allows the ordination of both women and (in certain presbyteries) non-celibate gays and lesbians as clergy. like the pc(usa), however, the pca accommodates different views of creation. the pca strives for racial reconciliation. the pca is unilaterally pro-life, believing life begins at conception. unlike the pc(usa), the pca has no ecumenical relationship with organizations which accept denominations that they perceive to have strayed from orthodoxy, such as the world council of churches or world communion of reformed churches. due to problems related to church property when splitting from the pc(usa), in the pca all church buildings belong to the local church, which gives the pca a slightly more congregational church structure than most other presbyterian structures.
