The truth of the matter is that we are not all the same in what we believe and practice as Christians somethings are right and somethings are wrong. I believe for good reason what the Orthodox Church teaches. You could read the words of our Lord and Savior Jesus Christ regarding Holy Communion for children I have put forth a few. There is a right and a wrong. The Roman Catholic Church used to not deny children Holy Communion up to about 900 years ago. I might add there was a time when the did not deny the cup to the laity as well. The Orthodox Church has remained faithful to what has always been practiced and taught by way of the traditions and practices of the Orthodox Church and in accordance with Holy Writ. I once new a Priest who used to tell some of us to use our minds but follow our hearts. He also believed that the Orthodox Church is the Catholic Church. As you know the Latin or Roman Catholic Church of today is much different than it was 1000 years ago.
26 And as they were eating, Jesus took bread, blessed and broke it, and gave it to the disciples and said, "Take, eat; this is My body."
27 Then He took the cup, and gave thanks, and gave it to them, saying, "Drink from it, all of you.
13 Then little children were brought to Him that He might put His hands on them and pray, but the disciples rebuked them. But Jesus said, "Let the little children come to Me, and do not forbid them; for of such is the kingdom of heaven."
Was not our Lord and Savior Jesus Christ crucified for children as well irrespective if they have reached the age of reason of 7 years old or so. I didn't even reach the age of reason until I was an adult and even then I'm not sure I would call it that.
