"When the sun had gone down and it was dark, behold, a smoking fire pot and a flaming torch passed between these pieces." Genesis 15:17

What was flying over the covenant?

In Genesis 15, Abraham splits the covenant animals in two — but does not cut the birds. This seemingly minor detail carries a theological weight that runs through the entire Scripture.

This book investigates the typological silence of the intact birds: who they represent, why they were left uncut, and how this gesture anticipates the atoning work of Christ — the covenant-bearer who passes through death without being broken.

Rooted in Biblical Hebrew exegesis and in dialogue with the Reformed theological tradition, the work weaves connections between the Abrahamic covenant, the Levitical system, and the New Testament.

Sérgio Moreira

Theologian with a Master's degree in Theology, Christian Formation teacher, and active member of a Presbyterian church. His intellectual journey is marked by deep engagement with the biblical languages — Hebrew and Greek — and a particular interest in hermeneutics and Old Testament typology.

The Uncut Birds is born from a conviction that the Old Testament is not merely a prelude to the New, but a rich and articulate presence of the same Gospel — waiting to be read with eyes that see Christ in every covenant, every rite, every detail.

The work is the fruit of years of research, pastoral reflection, and a deep love for the Word.
