I think it is accepted that the Trinity is impossible to fully understand.
But as far as I have been taught it (Lutheranism, Church of Sweden) for a Christian believer it is NOT wrong to say that Jesus is God.
But Jesus is also Gods son and it's ok to find this confusing, as long as you believe in it (according to the creed).

However my church has gone increasingly insanely politically correct. Can't take them seriously anymore because they change their minds about everything all the time! Lately, anything that Paul or Jesus or any of the writers of the evangeliums say.... that is not "politically correct".... they simply dismiss as irrelevant, or a personal opinion of the writer. At the rate they are going, it won't be necessary to even believe in God, salvation etc, in about a decade from now! As they try to keep up with the times, they also undermine their own credibility.
