In this sermon, the speaker addresses the primacy of the Romish sea, which refers to the authority of the Roman Catholic Church. The speaker acknowledges that the adversaries of the Church have good reason to maintain this primacy, as they believe their dependence lies in it. However, the speaker argues that this supremacy was established by the will of man, not divine authority. The speaker emphasizes the importance of unity in adhering to God and the Gospel as the only rule of a good and holy life. The speaker also addresses the accusation that the preaching of the Gospel leads to licentiousness, arguing that it is not the fault of the ministers of the Gospel but rather the result of individuals' rejection of God's authority.

In this sermon, the preacher discusses the nature of Scripture and the question of its verency or inerrancy. He recommends a clear and simple exposition of the inspiration of Scripture by Rene Posh as a valuable resource for understanding this topic. The preacher then moves on to discuss Mark's Gospel, emphasizing the importance of living out the moral standards of God rather than just performing religious rituals. He highlights how Jesus taught and met people in various settings, including peasant homes, fields, and even a stable, showing that God can be encountered outside of traditional religious spaces. The preacher encourages the church to be a place where people can meet God and where believers can impact others to encounter God as well.

J.H. Newman addresses the errors within the Roman Church regarding the sacrifices of Masses, emphasizing the distinction between the sacrifice of Christ's death and the belief that masses can serve as a separate atonement for sin. The sermon delves into historical observances surrounding the sacrifice of masses and condemns the practice of turning Mass into a means of financial gain, highlighting the dangers of such impostures. Various passages from Burnet, Bishop Bull, and others are cited to illustrate the corruption and idolatry that have infiltrated the Mass, leading to a distortion of true worship and faith.
