In "Like Father, Like Son" Tom Smail answers these questions, asserting that we are most fully human when we reflect the relationships between Father, Son, and Holy Spirit. Smail explores the concept of image in detail from various angles, including the biblical accounts, the theological history of the concept, and the implications of being created both male and female.

Smail also discusses our likeness to each part of the Trinity, focusing in particular on the initiating love of the Father, the responsive love of the Son, and the consummating love of the Spirit. Interacting with major modern thinkers while also speaking to issues of everyday concern, Smail's "Like Father, Like Son" is an intelligent discussion celebrating God as Father, Son, and Spirit, the threefold source of our created human existence.
