Ignatius of Antioch, writing only 70 or so years after the Resurrection of Jesus:
See that ye all follow the bishop, even as Jesus Christ does the Father, and
the presbytery as ye would the apostles; and reverence the deacons, as being the
of God. Let no man do anything connected with the Church without the bishop. Let
that be deemed a proper
Eucharist, which is [administered] either by the bishop, or by one to whom he
has entrusted it. Wherever the bishop shall appear, there let the multitude [of
the people] also be; even as, wherever Jesus Christ is, there is the Catholic
Church. It is not lawful without the bishop either to baptize or to celebrate a
love-feast; but whatsoever he shall approve of, that is also pleasing to God, so
that everything that is done may be secure and valid.
The Catholic Faith was alive and well even then. So well, that we were having problems and having to correct one another.
And then there was the lions and persecutions.
Also, before you get all happy, love-feasts were what they called the Eucharist (Mass). Love is a pretty broad term.*
*Feel free to use that statement when someone wants you to say "I love you".
