14 What will you answer a priest who says to you, “The church does not seek your gifts, because you have adorned the heathen temples with gifts. The Altar of Christ rejects your gifts, because you have made an altar for idols, for the voice is yours, the hand is yours, the subscription is yours, the deed is yours. The Lord Jesus refuses and rejects your service, because you have served idols, for He said to you: 'You cannot serve two masters.' The Virgins consecrated to God have no privileges from you, and do the Vestal Virgins claim them? Why do you ask for the priests of God, to whom you have preferred the profane petitions of the heathen? We cannot take up a share of the errors of others.”
