Also - Ask yourself if you are minimizing God … I ask this because many non-Catholics [and I too was one once

] feel that Catholics don’t really focus on Jesus or God - minimizing the Godhead and are more focused on Saints - elevating them to godlike status etc … for example - many Protestants say at the last supper that Jesus could not really have given His Body and Blood to the Disciples because he was standing there - so obviously Jesus meant the last supper as a symbolic or metaphorical event …
However, what I found is that Catholics really believe that Jesus is God - that His promises are true … that when He said to the disciples at the last supper - This is My Body … This is My Blood … he meant what He said - it really was His Body and His Blood … How, Why … Its a mystery - but it is … and since He is God - He can do that …stand there offering His Body and Blood … similarly - He promised that as often as we do this participation in the Body and Blood - we do do so in 'remembrance" of Jesus … as St Paul said - we are participating [in the Jewish sense of remembrance and participation] in the Life death and Resurrection - the Body and Blood of our Lord Jesus Christ … My God is an awesome God … He can do whatever He promises, desires, wants - regardless of my ability to comprehend and understand and outside the laws of science, physics, mathematics, etc … He is the Alpha and the Omega - He was, He is, He ever shall be … outside time and space … I do not have to understand - I only need to believe …
