no, it was actually the opposite. The early christians showed by their writings (including so-called church fathers) that they believed Jesus and Jehovah were two separate beings.
New Catholic Encyclopedia says: “The formulation ‘one God in three Persons’ was not solidly established, certainly not fully assimilated into Christian life and its profession of faith, prior to the end of the 4th century. But it is precisely this formulation that has first claim to the title the Trinitarian dogma. Among the Apostolic Fathers, there had been nothing even remotely approaching such a mentality or perspective.”
The Encyclopedia Americana says: “Fourth century Trinitarianism did not reflect accurately early Christian teaching regarding the nature of God; it was, on the contrary, a deviation from this teaching.”

There are many translators who do not agree that the verse should be read the way trinitarians want it to be read.
Expressions which link together the name of the Father, the Son, and the Holy Spirit occurred very early in the History of the Christian Church. These are sometimes taken as expressions about the Trinity. The bible I've shown states a Trinity, as All persons (Father, Son, Holy Spirit) have not only the attributes of God throughout scripture but they all do the works of God and are Even Called God in scripture. And yes the early church also believed in a Trinity.
