The Saints are dear brothers who have struggled like us and have departed to Paradise. They are not dead, but are sleeping, as our Lord said (Jn 11:11) and as St. Paul called them.
Our early fathers spoke clearly and in detail about our relationship with Saints. The Saints in Paradise are the triumphant members of the same one church in which we are militant members. We, the triumphant and militants, are members of the Church, which is the one Body of our Lord Jesus Christ. The triumphant become invisible members because of the death of their bodies, and then militants are the visible ones. This is man’s point of view, but in God’s sight, we are all a visible holy family.
