In God - 3 Subsistences

Here we see very clearly laid out for us 3 Divine Persons in one Essence, and the Divine Persons are all mentioned as having the same name; that is, the Name of God. "In the name", the One Essence, of the Father and of the Son, and of the Holy Spirit. Each of these Divine Persons and all of them together have given Christ's Church this command. Even though the command was given by the Son to His disciples, yet He, the Son, is speaking for the other 2 Persons who are "of" the same Name. These Persons exist together in the Divine Essence; they subsist there as distinct Persons in the Divine Essence.
