As I see it, there appears to be no mechanism of reform open to the laity.
The only option available to the laity is to rear up righteous sons. Then in 50 years ( maybe) these sons will be in the leadership positions to make reform possible. So?...Does that sound like a rational plan? A half century or more to see any meaningful change and even that is not guaranteed since exiting homosexuals promote and mentor other homosexuals.
Then if the Catholic leaves the corrupt church they are emotionally threatened ( in a cult-like manner) with eternal damnation. Wow! What a Catch 22.
Also, money is fungible, so there is no way to fully guarantee that donations to the Catholic Church are not going to promote more evil.
There is NO WHERE else to go. If the Catholic Church is not the Church Christ founded, then NONE are, and Christ was a liar and a deceiver, because He would have failed to keep His promise that the gates of Hell would not prevail against His Church.
"52 The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat? 53 Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you. 54 He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day. 55 For my flesh is meat indeed: and my blood is drink indeed. 56 He that eateth my flesh, and drinketh my blood, abideth in me, and I in him. 57 As the living Father hath sent me, and I live by the Father; so he that eateth me, the same also shall live by me. 58 This is the bread that came down from heaven. Not as your fathers did eat manna, and are dead. He that eateth this bread, shall live for ever.
59 These things he said, teaching in the synagogue, in Capharnaum.
60 Many therefore of his disciples, hearing it, said: This saying is hard, and who can hear it? 61 But Jesus, knowing in himself, that his disciples murmured at this, said to them: Doth this scandalize you? 62 If then you shall see the Son of man ascend up where he was before? 63 It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you, are spirit and life. 64 But there are some of you that believe not. For Jesus knew from the beginning, who they were that did not believe, and who he was, that would betray him. 65 And he said: Therefore did I say to you, that no man can come to me, unless it be given him by my Father.
66 After this many of his disciples went back; and walked no more with him. 67 Then Jesus said to the twelve: Will you also go away? 68 And Simon Peter answered him: Lord, to whom shall we go? thou hast the words of eternal life. 69 And we have believed and have known, that thou art the Christ, the Son of God.
