Evangelicals appeal to the early Church Fathers until the Fathers don't agree with them. Church Fathers speak about purgatory, the Eucharist, baptismal regeneration, the perpetual virginity of Mary, the authority of the Church, and many others.
They are always dismissed, reinterpreted, or ignored. Why? Bc you don’t find any traces of their Evangelical belief system. It did not exist in the 1st century.
