I recently learned (probably from Seth Godin) that there are two types of roles: certified and performative. Roles defined by certification can be faked; for example, a man can sit in a medical office, examine patients, and give advice without really being a doctor. Conversely, the mere act of executing a performative role makes it authentic: if you get on a stage and sing to an audience, you are a singer, regardless of whether you are “qualified” to be there.

Today, as for much of its history, being a Christian is primarily defined by certifications: baptism, confirmation, membership, statements of faith, etc. As a result, there are endless arguments (and divisions) regarding about who is “really” a Christian.

What if it was other way around? What if there was something we could do, such that the very act of doing it was proof that we are being united with Christ, regardless of our beliefs or motives?
