The term "missing link" isn't a term that's been in use among serious scientists in a very long time. Originally the term was meaningful because it was coined at a time when the hypothesis of humans and the non-human apes sharing a common ancestor was hypothesized, but not yet evidenced--but it was assumed that "the missing link" would be discovered.
In the last 150 years we've uncovered hundreds of transitional fossils belonging to a variety of hominin species.
As such the term "missing link" isn't meaningful, because the links between the transition from the last common ancestor of chimps and humans and modern Homo sapiens are multitude.
Here's a sampling:
Saying "has the missing link been found?" at this point is a bit like asking if there's any evidence that the earth is a globe.
ViaCrucis your referring to the so called manlike-hominid ancestor the precursor to both hominid and pongids-apes. As you said that link was never discovered. But that does not matter simply because you say we have the transitional fossils of both. Then the Holy Church does have a major theological problem to contend with. That being that both humans and apes must be in need of baptism and redemption as well. For the ape must have a soul too especially if the hominid ancestor is real and is related to Adam and the human race. But I do read that you do like the long time very much too. That being of many millions of years of which we have no evidence for except with bones and and fossils and what our unpredictable dating methods claim they be. And that does pose another problem too. For sin and death did enter the world firstly by Adam and Eve. Saying that the missing link doesn’t really matter be like saying we live on a flat earth : )
