Everybody's life of faith is different. The object of our faith is the Blessed Trinity. The question should not be "what makes us most comfortable" but what is Right Worship, Right Praise, Right Practice? I am fully Roman Catholic because I believe that living out His commands to Love God and neighbour, to love one another as He has loved us are things that can be fully done within the Catholic Way. We have the faith that comes to us from the Apostles. We have the Sacraments given us by the Lord. We have the charisms and movements started by great Christians like St Benedict, St John of the Cross, St Therese of Lisieux, St Vincent de Paul, St Ignatius Loyola, St Francis and St Clare of Assisi and so on. Our Lady does not disdain Catholic Christians appearing to St Bernadette at Lourdes, to the Fatima visionaries and as Our Lady of Guadalupe in the Americas. If the Holy spirit and the Mother of God have not abandoned the Church then why should anyone?
It is true that the Orthodox faith too has the Sacraments and, in part, the faith of the Apostles and offers much Right Worship,Right Praise and Right Practice. It is a way to Jesus, it is a lung of the Christian body, but it has not the fullness of the body.
