One Protestant ministry I find helpful equips protestants to understand the Christian gospel and contemporary paganism by drawing on the rich heritage of Irenaeus's apologetic defense against the pagans of his day. That particular ministries entire idea was seeing the connection between global paganism and gnostic belief in the first centuries of the church, realizing that Irenaeus had already done the heavy theological lifting, and the current need was to learn from him (and other church fathers) and recontextualize their insights for the church today.
For many protestants I've known, the church fathers and the ecumenical councils are seen as helpful, but never carrying the same authority as the Scriptures. The authority of councils and creeds is derived from the Bible, not the inverse.
