In other words, the Church is irrelevant in this world, what counts is our own 'personal relationship with God'. Many Protestants would agree with you there.
The modern heresy is the notion that Christ's Church has departed from the teaching of Christ and the so-called 'institutional church' has become the enemy of Christ. 
The New-Church claims that Our Lord would have whole-heartedly endorsed modern, secular, moral values and behaviours, abortion, same-sex relationships, euthanasia, cohabitation, etc, in fact everything that the True-Church had condemned for over 2000 years. They believe that the Holy Ghost has lain dormant for centuries and suddenly woke up in the 1960s and realised that the Church was on the wrong track up to the mid 20th century and hurriedly invented the New-Church which rectified it all.
Martin Luther et alii proposed the same arguments in the 16th century.
Christ's Church, however, despite all this is still with us.
