The church writes that Jesus is our "kingdom of god on earth".
(I did return yet to the roman catolic church but I grew up in it and read many booklets now.)
For the christian church the kingdom of god is already now on earth because Jesus Christ is ready to live in our heart, what we now have is already a partial fulfilment of the kingdom on earth but not yet the full glory.
The kingdom of god can be explained also as accepting the sovereinty of the lord. This means if someone accepts the sovereinty of God, only then she/is is in the kingdom. But the kingdom of God is not a tool to establish an adminstration over the earth, a real government with ministeres, princes, neither somewhere above in the stars nor here on earth, as it has been misinterpreted by the church too in the political arena, but only God in the midst of us, God dwelling in our hearts.
Imagine god would have that administration, kingdom in heaven and nobody would follow its rules? God would not need that governement than. Would he annihilate all nonbelievers? What he needs is ... that we love him. And only when we love God and recognize him, his figurative "reign" can become true. God only wants a kingdom in our hearts, that we love him. Those christians who recognize god believe they have heaven on earth, the kingdom on earth through Jesus Christ.
For christians Jesus is our kingdom on earth, his anointment with spirit, is comparable with the anointing oil that percolates the body and heals everything. The sense of becoming an anointed is to heal everyone. so Jesus healed and he heals us, Jesus christ is our kingdom of God that heals us.

After Jesus left the earth he said that the COMFORTER and HELPER, the spirit, would come and lead the church. There would be no direct communication - voice to ear - or channeling - until Jesus return. Jesus and father would act by the means of the comforter spirit. That Jesus RULES IN HEAVEN, or sits besides the father is merely a picture that discribes his authority in words of jewish king legends, but its nothing important that implies a real administration and does not deal with the threeholiness of god.
Therefore up to now, there is no direct communication or channel neither to the church, to the pope or the WT-Headquarter. Because we live in the era of the spirit where the Jesus and god opens the heart in the spirit, a era where Jesus lives further in his church, the church that is his mystical body. As jesus lives in you and me, and we are his - jesus - body, and we often dont think of it at all, we should really be thankful sometimes, about his mercy

Relating to the earthly life of Jesus Christ the church says that he was God and man and that he SPOKE the word of God to the hearts then and for all time once and ultimately to mankind.
