There’s some good advice above. I’ll add my 50 cents from a more “bookish” perspective.
- doesn’t understand why the rituals are necessary for worship - there’s suppose to be a “freedom in Christ” - he died for your freedom - which includes freedom from the need of rituals, etc. Catholic Church is all rituals and no freedom.
At it essence, the mass is about obeying JESUS’
command. The ritual of the mass was instituded by Christ at the first Eucharist: "Then he took the bread, said the blessing, broke it, and gave it to them, saying, “This is my body, which will be given for you;
do this in memory of me.” John 22:19. (emphasis supplied only to point out the command). If we are “doing this in memory of me,” then we require
some kind of ritual in order to obey Christ’s command. Whether the ritual is always the same or varies,
some ritual is needed in which we do “this” in memory of him.
The question then becomes, “what is in the ritual?” The answer comes from the Church, to which Jesus gave the power to made decisions in this matter. Matthew 13: 16-19 (Keys to the Kingdom, and the power to bind and loose). Thus, it is the
Church that decides the form of the ritual, and we are required to obey the Church’s decision in these matters because we are required to obey Christ who gave that authority to the Church.
The issues of freedom are, IMHO, a red herring. “Freedom” is the battle cry of Satan, who from the start said “I will not serve” (i.e., I want “freedom” from God’s commands). You can see the result. Authentic freedom is freedom from
sin, not avoidance of obediance to lawful authority.
- along with this freedom, one should be able to take communion without having to be a member of a certain church. How could a church refuse to let you take communion until your a member.
Again, the focus is on freedom, but that is the wrong focus.
When you take communion in the Catholic Church there are two (well, more than two, but for our purposes here I’ll say two) things happening. 1) You are receiving the actual body and blood of Jesus - regardless of whether you believe it or not. 2) You are stating by the very act of receiving communion that you believe
everything the Catholic Church teaches as being
required or “infallible.” Not part of what she teaches, all of it. (Note, some beliefs are “optional;” you could receive communion as a Catholic and hold a legitimate minority opinion on issues like the Shroud of Turin and many others).
So, for #2, If you are not Catholic, or don’t believe everything she requires, then you would be participating in deceit, even if you didn’t know it. The Church knows this, and wouldn’t want to condone deceit.
Worse, for #1, receiving the actual body and blood of Jesus in an unworthy manner is
dangerous. “Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the Body and Blood of the Lord.” 1 Cor 11:27. Thus, the person receiving communion in an unworthy manner may be subject to grave danger of destruction, both temporal and eternal.
The Church is being
merciful when she denies communion to non-Catholics.
Part of what your wife is struggling with here is that the Catholic Church is not just a club where, if you don’t like the rules, you join some other club. The Catholic Church is about the
reality of God; about the Truth in the absolute sense.
