In my opinion, only Catholics think that whenever Jesus or scripture mention “church”
Personal opinion,or matter of one’s own interpretation dont count much’first of all not every thing is written in the Bible neither the word Catholic not Trinity as in **John 21:25 But there are also many other things that Jesus did; if every one of them were written down, I suppose that the world itself could not contain the books that would be written…

Matthew 16:16-18 7 And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven.18 And I say to thee
: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. ** Acts 20:28 Keep watch over yourselves and over all the flock, of which the Holy Spirit has made you overseers, to shepherd the church of God that he obtained with the blood of his own Son.**Jesus taught the Apostles for 3 years and instruction everything ,even at the resurrections some still doubted Jesus rebuked then for their disbelief, so dont keep doubting.
2 Thessalonians 2:14 For this purpose he called you through our proclamation of the good news,so that you may obtain the glory of our Lord Jesus Christ.
15 So then, brothers and sisters, stand firm and hold fast to the traditions that you were taught by us, either by word of mouth or by our letter. In the apostolic preaching. . .
76 In keeping with the Lord’s command, the Gospel was handed on in two ways:
- orally “by the apostles who handed on, by the spoken word of their preaching, by the example they gave, by the institutions they established, what they themselves had received - whether from the lips of Christ, from his way of life and his works, or whether they had learned it at the prompting of the Holy Spirit”;[33]
- in writing “by those apostles and other men associated with the apostles who, under the inspiration of the same Holy Spirit, committed the message of salvation to writing”.[34]
. . . continued in apostolic succession
77 “In order that the full and living Gospel might always be preserved in the Church the apostles left bishops as their successors. They gave them their own position of teaching authority.”[35] Indeed, “the apostolic preaching, which is expressed in a special way in the inspired books, was to be preserved in a continuous line of succession until the end of time.”[36]
78 This living transmission, accomplished in the Holy Spirit, is called Tradition, since it is distinct from Sacred Scripture, though closely connected to it. Through Tradition, “the Church, in her doctrine, life and worship, perpetuates and transmits to every generation all that she herself is, all that she believes.”[37]
“The sayings of the holy Fathers are a witness to the life-giving presence of this Tradition, showing how its riches are poured out in the practice and life of the Church, in her belief and her prayer.”[38]
