In hoc cognoscent omnes (In this all shall know) is the sixth antiphon during the Washing of the Feet ceremony on Maundy Thursday.
The antiphon comes from John 13: 35. It is one of the eight antiphons sung during the ceremony, and reminds us of the example Our Lord gave us, in showing humility and charity to our neighbor.
In hoc cognoscent omnes is here interpreted by The Monks of Glenstal Abbey.

Ant. In hoc cognoscent omnes,
Quia mei estis discipuli,
Di dilectionem habueritis ad invicem.
V. Dixit Jesus discipulis suis.

That ye are my disciples,
If ye have a love for one another.
