For me - a big part of the problem with Christians and Roman Catholic ones in particular, is that we are taught and we repeat it at every mass ... that we are not worthy.  Yes ... we say God is Love; and to Love God is to be Love and Loving ... and I suggest ... that need to begin with embracing our being beloved children of the Divine.   To me - we are loving our neighbours as ourselves ... and that is the problem - because we do not have a healthy love of self and embrace how God made us and others.  We are taught self-loathing ... and that gets reflected in all our relationships ... including with God and neighbours ... particularly if they are slightly different to us.
