John 13:34-35
The context
Jesus has washed the disciples' feet, identified the betrayer, and watched Judas leave into the night. The farewell discourse begins here. He speaks of being glorified and of the disciples' inability to follow him now, then gives the command that will mark them out among others.
What it establishes
It establishes that the standard for the community's love is Jesus' own love, not a general benevolence, and that this love is presented as a visible identifier to outsiders rather than a private sentiment.
What it does not establish
It does not say love replaces teaching or belief. The command sits inside a discourse full of claims about who Jesus is; it is not offered as a substitute for them. Nor does it promise that outsiders will be converted by watching, only that they will recognize the disciples.
